Back in 2019, we published Quick Wins for your Data Visualizations, a guide to help city staff create clearer, more effective charts for budget documents, council presentations, and reports. It's been one of our most-read posts.

We've now updated it with interactive examples that let you experience the principles firsthand. You can toggle between cluttered and clean chart styles, see why bar charts beat pie charts for comparing values, and watch how line charts reveal trends that other formats hide.

If you read the original, it's worth another look. If you haven't, now's a good time to check it out.
