A bad chart can tell a completely wrong story. Here's how to visualize data honestly and effectively.
Chart Selection
Comparison: bar chart. Trend over time: line chart. Proportion: pie chart (only for 2-5 categories). Distribution: histogram. Relationship: scatter plot. That covers 90% of use cases.
Common Mistakes
Y-axis not starting at zero (makes small differences look huge). 3D charts (distort proportions). Too many colors. Pie charts with 15 slices. Dual Y-axes (confusing). Missing labels and titles.
