Chart Smith

Each round gives you a dataset and a communication goal. Choose a chart type (bar, line, pie, scatter, stacked and more) and toggle encoding options, with a live canvas preview. Submit to the critic, who scores 0–100 and lists deductions for misleading or mismatched choices. Build the clearest, most honest chart for each goal across the run.

• Pies suit parts of a whole, lines suit trends, scatter suits relationships.
• 3D effects, dual axes and truncated baselines draw deductions.
• Six rounds, each worth up to 100 points.

• Desktop: click a chart type and toggle encoding buttons, then Submit to critic.
• Phone & tablet: tap the chart and encoding buttons, fully touch-friendly.

• Daily: a shared seeded set of briefs.
• Practice: fresh randomized briefs each run.

• Match the chart to the goal first; a wrong type loses more than a bad option.
• Leave 3D and dual axes off, they almost always cost you points.

Chart Smith is about choosing the right chart and avoiding deceptive encodings.

• Skills: data visualization, choosing charts, encoding data
• Best for: roughly grades 7–12 (ages 12+)
• For parents & teachers: picking the chart that tells the truth.

Choosing a chart type and encodings to meet a communication goal is the core judgement of statistical graphics.

The original framing is that each round supplies a goal, not just a dataset.

Without a stated purpose there is no best chart, which is why "which chart should I use" has no general answer. A pie is poor for comparing similar shares and fine for showing one dominant part; the goal is what makes the choice decidable.
