# Charts — Third-Party Libraries The `@datagrok/charts` package is distributed under the MIT license that covers the rest of the `public/` repository (see [`../../LICENSE.md`](../../LICENSE.md)). It incorporates the open-source components listed below; this file reproduces the attribution and notices required by their respective licenses. Charts bundles a number of charting and graph libraries. Most are under permissive licenses (Apache-2.0, MIT, BSD-3-Clause, ISC). One dependency (`circosJS`) ships with a license discrepancy that is explained in its section below; readers integrating the published plugin into a downstream distribution should review that note. --- ## 1. Bundled in the published artifact (`dist/`) ### Apache ECharts (5.x) and echarts-gl (2.x) ECharts is the primary visualization engine behind the Charts package (chord, sankey, sunburst, radar, tree, treemap, …); echarts-gl provides the WebGL-backed surface plot. - Upstream: https://echarts.apache.org/ — https://github.com/apache/echarts - echarts-gl: https://github.com/ecomfe/echarts-gl - License: **Apache-2.0** (echarts), **BSD-3-Clause** (echarts-gl) Apache-2.0 (echarts): ``` Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.

We follow the upstream/`package.json` declaration and treat circosJS as ISC; downstream distributors of the published Charts plugin who require a strict audit-trail interpretation should re-confirm the license with the upstream maintainer.

Linked at runtime via the Datagrok platform (webpack externals) These libraries are not bundled into Charts' `dist/` — they are provided once by the platform host and shared across all packages. | Component | Version | License | Upstream | |-----------|---------|------------|-----------------------------------------| | RxJS | 6.x | Apache-2.0 | https://github.com/ReactiveX/rxjs | | cash-dom | 8.x | MIT | https://github.com/fabiospampinato/cash | --- ## 3. Development-only dependencies Tools used during the build/test cycle (not in the runtime tree, not bundled): the `datagrok-tools` CLI transitively pulls in `puppeteer-screen-recorder`, which references `@ffmpeg-installer/ffmpeg` (LGPL-2.1) and `@ffmpeg-installer/win32-x64` (GPLv3). These binaries are **not** redistributed as part of the published Charts plugin and impose no obligation on users of the plugin. `d3-cloud` (BSD-3-Clause) is a build-time-only dependency that backs `echarts-wordcloud` typings.
