Lisa Rost from Datawrapper just shared her presentation from a recent data conference, and it provides great dataviz tips on slides 36-56. (Don’t let the number overwhelm you! They are simple, beautiful slides.)
Data viz is all about representing numbers in a visual way/using visual elements. You can do this in a few ways: counts, lengths, area, colour, or 3D. Here are a few tips from this awesome presentation:
- If you want to make it easy for readers to understand your chart, visualize your data with counts and/or length (plus these are generally easier to work with).
- Make it easy for readers to read the labels (make sure there’s enough space for the label)
- Bring labels as close as you can (within chart, instead of floating on top/below)
- Explain what’s important about the chart in the title or using annotations, and include context when needed
- Use colours that colour-blind readers will be able to distinguish
My favorite tidbit: “If readers don’t get our charts, it’s our fault.”
