Online Chart Makers
Start with the chart form, not the file format. This hub groups chart makers by comparison, trend, distribution, relationship, flow, and target-tracking work.
Workflow
Compare
Use bar, Pareto, comparison, or bullet charts when the reader needs to rank categories or check a value against a target.
Explain change
Use line, area, waterfall, funnel, or timeline charts when order, sequence, or movement matters.
Inspect spread
Use histogram, box plot, scatter, bubble, or heatmap pages when the question is about distribution, relationship, or density.

Questions before you start
Should I choose the chart page or the data import page first?
Choose a chart page when you already know the visual form. Choose a data import page when you only know the file format.
Do all chart maker pages export images?
Yes. Chart maker pages expose PNG and SVG exports, with report-oriented pages adding Markdown or summary outputs.
