Chart Selection Best Practices
Understanding when to use which chart visualization technique is crucial for clear data storytelling:
Pie Chart
Purpose: Simple proportional slice splits.
Best Use: Budget allocations, market share partitions, survey yes/no splits.
When to Use: Portions of a single whole summing to 100% (limit to 5-6 slices max).
Line Chart
Purpose: Continuous interval progressions.
Best Use: Stock values, website visitors monthly trend, monthly temperatures.
When to Use: Data changes continuously over time and tracking rate/direction of change matters.
Doughnut Chart
Purpose: Modern parts-of-a-whole views.
Best Use: Asset ratios, expense breakdowns, demographic proportions.
When to Use: Identical to Pie charts but offers cleaner legibility by removing heavy visual weight at the center.
Polar Area
Purpose: Cyclical direction scales.
Best Use: Wind speed vectors, seasonal demographic cycles, temperature cycles.
When to Use: Category angles are equal, but values dictate radial circle expansions.
Radar Chart
Purpose: Multi-variate subject profiles.
Best Use: Player statistical attributes, competence profile comparisons.
When to Use: Plotting three or more quantitative variables on axes originating from the center.
Histogram
Purpose: Range interval frequency spreads.
Best Use: Age distributions, test score distributions, salary counts.
When to Use: Plotting quantities within contiguous numerical intervals or range groups (bins).
Box & Whisker
Purpose: Median quartile variations.
Best Use: Test scores deviations, manufacturing tolerances, research statistics.
When to Use: Depicting five-number statistics (minimum, quartiles, median, maximum, outliers).

Frequently Asked Questions
Q When should I use a Bar chart vs a Line chart?
Use Bar charts to compare discrete categories (e.g. quarterly revenue across departments). Use Line charts to visualize continuous trends over time (e.g. monthly website traffic growth or stock price movements).
Q Can I export charts as vector SVG for Illustrator or Figma?
Yes! Downloading as SVG preserves vector path shapes and editable text layers, allowing you to seamlessly scale or style the chart in Figma, Sketch, or Adobe Illustrator without pixelation.
Q Is my corporate or financial data kept private?
Yes, 100%. All chart rendering happens entirely client-side using HTML5 Canvas and SVG. No tabular data or uploaded CSV files are ever stored on external web servers.
