three.js (mrdoob/three.js) is an open-source JavaScript library for real-time 3D graphics in the browser, released under the MIT license. It renders through built-in WebGL and WebGPU renderers, with SVG and CSS3D renderers shipped as separate addons. It's the library behind the scene-graph API shown in its own README example: a camera, a geometry, a material, and a mesh composed into a scene and redrawn each frame through an animation loop.

Chart.js is an open-source JavaScript library at chartjs/Chart.js for drawing charts onto an HTML5 canvas element, the output format its own GitHub description names directly. The project has stars and forks on GitHub, ships under the MIT license, and organizes its documentation into getting-started, data-structure, configuration, chart-type, and axes sections rather than one long page.

Immich is a self-hosted photo and video management app written mostly in TypeScript: a NestJS backend, a SvelteKit web client, and Flutter mobile apps. It backs up photos automatically from your phone, clusters faces, indexes content with CLIP embeddings for text search, and plots shots on a map — the feature set Google Photos users expect, running on a server you own instead of a vendor's cloud. It's licensed AGPL-3.0 and sits at 109,695 GitHub stars.

Apache ECharts is an open-source charting and data visualization library maintained at apache/echarts, written in pure JavaScript and rendered through zrender, a canvas library built for the project. The GitHub repo is available under the Apache-2.0 license, and the README documents an npm package, a CDN build, and extension packages including ECharts GL for 3D and WebGL.
