Chart playground

Same data. Better choices.

One dataset: revenue by region. Change the chart type and styling, and watch the clarity score react. Decluttering, live.

About this exercise

One revenue-by-region dataset and a handful of design choices. Every change moves the clarity score, so you see decluttering principles at work.

How it works

  1. Choose a chart type: bar, column, line or donut.
  2. Pick a colour strategy, sort the values, highlight the leader and declutter the labels.
  3. Reach a clarity score of 80 or more to complete the exercise.

Principles you practise

  • A horizontal bar chart is a solid choice for comparing categories.
  • Sorted descending — the ranking is instant.
  • One calm accent. Colour stays available to mean something.
  • Highlighting the top region gives the eye an instant answer to “who won?”.
  • Decluttered — only the ink that carries meaning remains.

What to avoid

  • A line implies a time order. Regions are categories — the line invents a trend that isn’t there.
  • 7 slices is far too many for a donut. Angles this similar are impossible to compare.
  • Every bar a different colour signals “these are different categories” — but they’re the same metric. Colour with no meaning is noise.
  • Heavy value labels everywhere compete with the data. Strip what you don’t need.
