6th December 2022 – Streamlit: making interactive data-apps in Python the user-friendly way

In our next session Allee Tanner from the Jean Golding Institute will introduce us to Streamlit, a Python library that can quickly turn your scripts into web frontends and dashboards.

6th December 2022 – Streamlit: making interactive data-apps in Python the user-friendly way

Tuesday 6th December, 3-4pm
Room G.11, Fry Building, Woodland Road, University of Bristol (view map)
In-person talk (remote option available)

Streamlit is a Python library for rapid prototyping, templating and deploying data-science dashboards and web-apps (a desktop-app option is also in development). A core goal is simplicity, allowing even beginners to create data-apps within minutes, harnessing powerful graphical packages while avoiding the complexity these often entail. Python remains at the forefront of research coding languages, being relatively easy to learn, having a wide selection of professionally-developed 3rd-party libraries, all supported by a dynamic, responsive community.

Good research relies on clear communication. The power of Streamlit is in providing an accessible way for us to share the messages emerging from underlying, complex work. While graphics libraries to visualise analyses exist, most notably in JavaScript, often these require considerable coding expertise, or may be inflexible in their application. With intelligent API design – as Streamlit characterises – these complexities can be managed, renewing focus on the research message.

This session aims to give an overview of Streamlit, demonstrate the ways in which it can be used in research, and cover some basics of the Streamlit API. We hope the session will encourage researchers to explore how Streamlit might be used in their work.

1st November 2022 – Cognitive Processing of Magnitude In Data Visualisations

We’re thrilled to announce a new series of DataViz talks for the start of the 2022/23 academic year! As ever, our events our open to everyone and you do not need to be a member of the University of Bristol.

We start with an in-person talk (remote option available) from Duncan Bradley @duncanbradley_ on the Cognitive Processing of Magnitude In Data Visualisations.

1st November 2022 – Cognitive Processing of Magnitude In Data Visualisations

Tuesday 1st November, 3-4pm
Royal Fort House, University of Bristol

In-person talk (remote option available)

Data visualisations allow viewers to efficiently appraise many facets of a dataset. Systematically manipulating data visualisation designs helps us understand the processes involved in interpreting presented information. In this seminar, I will discuss a series of experiments revealing how axis limits inform judgements of how large or small plotted values are. These findings contribute to our understanding of the cognitive processing of magnitude in data visualisations, with potential consequences for design recommendations. This work provides insight into how specific design choices might help communicate messages effectively, or might mislead viewers.

Duncan Bradley

Duncan Bradley is a final-year PhD student in the Division of Neuroscience at the University of Manchester. He is interested in how data visualisations can leverage the human cognitive system to effectively convey messages. His research explores the cognitive processes involved in extracting meaning from data visualisations and the influence of design choices on the interpretation of presented information.

Digital Security by Design and the Secret Life of Data

Genevieve Liveley
Professor of Classics, University of Bristol

When we think about the security of data on our phones and computers, we might think about passwords and permissions, or about data encryption – but we rarely think about what our data looks like, or what is does as it moves around hidden inside our phones, computers, digital devices, our apps and networks. This invisibility – this secret life of data – makes it difficult to communicate the benefits of innovations such as Digital Security by Design (DSbD) and to imagine futures where this paradigm shift in technology can be most beneficial. This presentation explores the value of creative storytelling as one way to explore the sociotechnical impacts of DSbD.

Genevieve is Professor of Classics, RISCS Fellow, and Turing Fellow at the University of Bristol. As a narratologist, she has particular research interests in stories and their impact on futures thinking – especially in the context of emerging technologies and cyber security. She leads the Futures strand for the UKRI’s Digital Security by Design (DSbD) Discribe Hub+ programme, and as RISCS Fellow, heads the ‘Anticipation and Futures Literacy’ research theme.

Mapping Intercultural Conversations

Jo Crow
Associate Professor in Latin American Studies, University of Bristol

The Mapping Intercultural Conversations project started in 2014, with a series of workshops involving many different people in Chile and the UK who wanted to share knowledge and ideas about Mapuche history, interculturalism, representation and self-representation, memory and digital culture. It centres around three prominent Mapuche leaders in early 20th century Chile, whose contested legacies live on to this day: Manuel Manquilef, Manuel Aburto Panguilef, and Venancio Coñuepán. We asked ourselves the questions: Why and how did these figures become the important political spokesmen that they did? Part of the answer lies in the vast web of connections that they built up over the years. The project webpage invites you to look into their complex social networks, and in turn serves as an entry point to a history of Mapuche political activism in Chile which challenges overly-simple identity categories.

Jo’s research interests include Chilean cultural history, nationalism and nation building, and Mapuche history, intellectuality and politics. Her new research project investigates the production of knowledge and circulation of ideas about race and indigenous cultures in twentieth century Latin America, focusing specifically on Chilean-Peruvian intellectual networks.

Corpus Creation in Digital Humanities: A Work in Progress

John David Vandevert
Postgraduate in Musicology, University of Bristol

When dealing with historiographical information and its contemporary development in Humanities research, it is well-known that a researcher must examine how “historical importance” and “historical truth” are being comprehended. But in Digital Humanities work, the requirement is greater, as leading any project is a subjectively-created corpus of aggregated data. Ergo, in the inescapably flawed process of “datafication,” how do researchers grapple with questions of ‘vantage point’ and epistemic authenticity? In this talk, I will introduce some early challenges regarding corpus creation in my digital project on contextualizing Russian Hip-Hop’s aesthetics and the need for a reexamination of how a corpus is created.

John is a postgraduate in the faculty of Musicology, currently studying Russian Hip-Hop, specifically Dmitry Kuzenstov’s 2020 album “Hoshkhonog”, to guage how the genre’s aesthetics embodies or negates the presence of the historically-defined quality of “musical Russianess.” His main interest lies in understanding how beliefs on national identity and cultural belonging, along with accumulated life experiences and personal ideologies present themselves in a composer’s musical vocabulary. He plans on pursuing Doctoral studies on the subject in the fall of this year.

Mapping American Socio-Commercial Networks

Thomas Larkin
Augustine Heard Fellow, University of Bristol

Mapping American Socio-Commercial Networks is a pilot digital humanities project intended to demonstrate the extent of networking and mobility between China and the West in the nineteenth century. Intended to draw together researchers from Bristol, Aix-Marseille, and Vancouver, the project catalogues foreigners, their networks, and their movements in nineteenth-century China using GIS and Social Network Analysis. The ultimate goal is to produce a user-friendly digital platform for visualising socio-commercial networks and transnational mobility. Aimed at researchers and students, the platform will both serve as a reference tool and address the need for alternative pedagogical approaches to teaching global history.

Thomas is an historian of China and the United States with particular interests in global-microhistorical and transimperial methodologies. His research engages broadly with themes related to culture, gender, race, and identity construction in colonial and (semi)colonial spaces.

trajVis: a web tool for viewing animal movement data on interactive maps

Dr Raff Mares, Data Analyst at Internet of Elephants

Movement data from wild animals, invaluable for conservation purposes, are increasing in volume as tracking devices become smaller and cheaper. Similarly, the detailed interactive maps that can put these data into context are ubiquitous and super easy to use. Putting the two together, however, isn’t straightforward: there is no tool that lets you easily playback movement data like a video on an interactive map. As the data scientist at Internet of Elephants, a mobile games company that uses wildlife data to tell conservation stories, I needed a quick and efficient way to view and share the amazing animal tracking data we were getting from our conservation partners. I created trajVis, an open-source web tool for visualising trajectory data on interactive maps, to fill this exact need – no installing software, manipulating data or coding required.

Raff is a wildlife biologist and web developer based in Bristol, with an interest in animal movement, spatial data visualisation, and games for conservation. They’ve always been fascinated by how animals move in their environment and have been lucky to study this from ocelots to meerkats, across the rainforest and desert.

climatearchive.org: the Google Earth for climate data

Dr Seb Steinig, School of Geographical Sciences, University of Bristol

We can only fully understand the past, present and future climate changes by bringing together data and process understanding from a broad range of environmental sciences. In theory, climate modelling provides a wealth of data of great interest to a wide variety of disciplines (e.g., chemistry, geology, hydrology), but in practice, the large volume and complexity of these datasets often prevent direct access and therefore limit their benefits for large parts of our community.

We present the new online platform “climatearchive.org” to break down these barriers and provide intuitive and informative access to climate model data to our community and the public. The current release enables interactive access to a compilation of 109 climate model simulations covering the climate evolution of more than 500 million years. Key climate variables (temperature, precipitation, vegetation and circulation) are displayed on a virtual globe in an intuitive three-dimensional environment and on a continuous time axis. The software uses the JavaScript library “Three.js” for real-time GPU-accelerated rendering of complex climate model data. We use this technique to not only explore our Earth, but also the wider solar system and even fantasy worlds like “Dune” and “The Wheel of Time”. “climatearchive.org” runs in any web browser — including smartphones — and promotes data exploration, appeals to students and generates public interest.

Seb is a postdoctoral researcher at the School of Geographical Sciences at the University of Bristol. They are currently using numerical models and paleoclimate data to understand how and why climate has changed in the past. They are particularly interested in how we can share our climate model data and research findings with the wider public.
