Chart and Diagram Generators
Generate bar, line, pie, donut, scatter, radar, Gantt, Sankey, heatmap, funnel, treemap, and dozens more charts and diagrams from your own data in one visualization hub.
This hub brings together the chart and diagram generators people reach for when they need to turn numbers, categories, ranges, or relationships into a visual they can share. It covers the everyday charts (bar, line, pie, area, scatter), comparison and composition charts (grouped and stacked bars, donut, funnel, waterfall), statistical views (box plot, heatmap, parallel coordinates), and specialized layouts (Gantt, Sankey, chord, network, radar, quadrant, timeline, word cloud).

Why this hub exists
Picking the right chart is half the work: seeing bar, line, area, and stacked variants side by side helps you choose the shape that actually fits your data instead of defaulting to a pie chart.
It groups composition, comparison, distribution, and relationship charts together, so you can move from raw values to a ready-to-share visual without hunting across unrelated pages.
Each generator is a standalone tool, so you can paste your own data, tune the styling, and export a chart for a report, slide deck, dashboard, or documentation page in one place.

FAQ
What kinds of data do these chart generators accept?
They are designed for pasted or uploaded tabular data such as category/value pairs, multiple numeric series, ranges with min and max, or hierarchical lists. Each tool documents the exact input it expects.
Which chart should I use to compare values across categories?
Bar, column, and grouped bar charts compare discrete categories well; stacked bars show both the total and the composition; radar and spider charts compare several categories across multiple dimensions at once.
Are these for static images or interactive charts?
The generators produce visual output you can review and export. Many render interactive charts that are also suitable for embedding into dashboards, reports, or documentation.
