Exercises for CHASE's Introduction to Information Visualisation

These exercises were prepared for the CHASE Arts and Humanities in the Digital Age event's workshop on Information Visualisation but they're also useful for people who want to learn more about data visualisations in cultural heritage and the humanities.

Exercise 1: compare simple text tools

Time: c. 5 minutes.

Goal: compare the ability of two different tools to help you understand a new text corpus

1.     Load the word cloud site

2.     Then, grab some text:

  • Open another browser tab
  • Go to http://pastebin.com/Nd0a86tm
  • Select and copy the 8 lines of text. The easiest way is to click into the box under 'RAW Paste Data'
  • Paste them into the text box on the Wordle site and hit 'go'
  • You can customise your visualisation using the menu. Which options create a more informative visualisation?

3.     Load the word tree site

  • Go to http://www.jasondavies.com/wordtree/
  • Paste the text into the 'Paste Text' box and hit 'Generate WordTree!' (Grab the text again from Step 2 if necessary)
  • You can click on words on the screen – which words produce the most options?

4.     Discuss

Bearing in mind that this is an unusual corpus, which tool gave you a better sense of its content? Why?

Are these tools better for exploring or explaining data? Why?

If tidying up the data provided – removing punctuation, making spelling consistent, etc – would improve the visualisation, then try editing the text and re-running the visualisation. Did it help? What else could you do?

Exercise 2: exploring scholarly data visualisations

Time: c. 10-15 minutes.

Goal: get hands-on experience and practice critical analysis.

Pair up with your neighbour to explore and discuss one of the visualisations listed on the following page.

Instructions

  1. In your browser, go to one of the sites below
  2. Take a few minutes to explore the visualisation
  3. Then discuss with your neighbour:
    • What do you think is being presented here?
    • Can you easily see where to start and how to use it?
    • What stories or trends can you start to see?
    • Does it work better at one scale over another?
    • Do you find it more effective at aggregate or detail level?
    • Does it present an argument or provide a space for you to explore and develop one?
    • What arguments (statements about the data) does the site present?
    • What have you learned from visualisation that you might not have learned from looking at the data or reading a description of it?
  4. Be prepared to report back to the group. e.g. summarise the site's purpose, visualisation formats and data types, or share unresolved questions or the most interesting parts of your discussion

HILT Crowdsourcing Slides and Exercises for Monday

Session 2: links to find a project you love! For non-English language projects, try Crowdsourcing the world's heritage.

Prompts for thinking about projects:

  • How clear was the purpose of the site? How well was it reflected in the 'call to action' and other text?
  • How easy was it to get started?
  • Were the steps to complete the task clear?
  • How enjoyable was the task?
  • Did the reward (if any) feel appropriate?
  • Looking at the site overall, does the project appear to be effective?
  • What is the input content? What is the output content?
  • What validation methods appear to have been used?
  • Who is the probable audience and what motivates them to participate?
  • How does the project let participants know they're making a difference?
  • Does the site support communication between participants?
  • How was the site marketed to potential participants?
  • Did the site anticipate your questions about the tasks?

Workshop: Information Visualisation, CHASE Arts and Humanities in the Digital Age

I've been asked to give a workshop on Information Visualisation for the CHASE Arts and Humanities in the Digital Age training programme in June 2015.

The workshop will introduce students to the use of visualisations for understanding, analysing and presenting large-scale datasets in the Humanities, enabling scholars to ask increasingly complex research questions.

Slides, sample data and instructions for exercises are downloadable here: CHASE InfoVis Handouts 2015.

Links for the various exercises are collected below for ease of access.

Exercise 1: Exploring network visualisations

Exercise 2: Comparing N-gram tools

Books

Newspapers

Exercise 3: Trying entity recognition

Workshop: Visualising Collections, Geffrye Museum

Ananda Rutherford organised a workshop for the Documenting Homes project at the Geffrye Museum, which  is researching visualisation models for presenting the archive and other collections information across digital platforms. The workshop is a chance to explore the role of visualisations in organising, interrogating and interpreting collections in context and to develop critical and planning skills for designing visualisations. It will include guided exercises for turning data in a spreadsheet into simple visualisations and an optional hour for trying out visualisation tools with your own data.

Contact me for the workshop slides and datasets. The exercises are below.
