Datawrapper utilities (GitHub)
This Datawrapper repository contains shared JavaScript utility functions for client-side data visualization, released under the MIT license.
About Datawrapper utilities (GitHub)
This repository contains shared code developed for Datawrapper's client-side data visualizations. It includes JavaScript and TypeScript utilities that developers can inspect and integrate into their own code. The shared library documents individual function imports as well as a package import, with helpers for work such as formatting chart columns and measuring color lightness.
The code is MIT-licensed. The repository also contains an API reference for shared methods and documentation for parts of the chart core. It is most useful when you already have a JavaScript project and a specific function to evaluate. People who want to upload a spreadsheet and build a chart through a graphical editor should visit the separate Datawrapper application. That hosted service has its own features and pricing.
