- 17. How to Begin
- 18. How to Begin The main thing to consider is: how will your Data Visualization be used? Is it for planning? Or advocacy? Are you trying to tell a specific story? Or are you trying to create a more neutral map to guide a process of discovery?
- 19. Planning Your Data Visualization ● What kind of data is best presented as a chart, as a diagram or as a map? ● How do you know what information to focus on and what to exclude? ● What is your overall strategy for change? ● What is your desired outcome? ● What will move your constituency or target?
- 20. Assessing Your Data ● What information should I collect? ● What types of information do I have? ● Do I have information worth using? ● What is my key message or desired outcome? ● What can I leave out?
- 21. Sorting and Sketching ● Card Sorting ● Persona & Scenarios ● Sketching
- 22. Assessing Your Media ● What is it for? How will it be published or distributed? ● How will your design live over time? ● On Paper ● On Screen ● Posters and Stickers
- 24. Clarifying Your Graphics ● What is most important? ● Keep it simple. ● Show comparisons, contrasts, and differences. ● Is the language clear and easy to understand?
- 25. Clarifying Your Graphics ● Is the choice of typeface clear and legible at a glance? ● Is your title clear? ● Do your graphics require a legend? ● Is your documentation clear?
- 26. More Tips ● Sketch out ideas on paper first ● The graphic has to tell a story ● Put your conclusion right there in the caption. ● Show the actual data, as much as you can. ● Show as few non-data elements as you can.
- 27. More Tips ● Minimize the number of steps required to interpret your graphic ● Provide context. Always use a scale and give sources. ● Learn some basic typography and a graphics application.
- 28. Evaluate and Iterate Testing your graphics with even a small number of typical users can provide useful insight for revising and improving your work.
