When you need to turn data into charts, this handles the whole pipeline: picking the right visualization from 26 chart types (line, bar, sankey, mind maps, even fishbone diagrams), extracting parameters from your data, and generating the actual image via a Node.js script. It's built on AntV and comes with detailed specs in the references folder for each chart type, so you know exactly what args to pass. The workflow is structured but not rigid. You analyze the data, consult the reference docs, build a JSON payload, and get back an image URL. Good for when you want visualization without reinventing the wheel on chart selection logic or rendering.
