This tool is powered by roughViz.js and helps you generate hand-drawn style charts directly in your browser. You can input chart data online without coding or importing complex files, then quickly create bar, horizontal bar, pie, and donut charts.

Compared with traditional chart tools, this page is better for communicating ideas, trends, and structure instead of strict numeric precision. It is especially useful for brainstorming, teaching, proposal drafts, and early-stage presentations.
