A unified model for representing syntax trees.

Validate unknown data with Valibot, the open source schema library with bundle size, type safety and developer experience in mind.

An Open Source JavaScript Visualization Library.

Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction.

Discover insights faster and collaborate seamlessly with interactive Observable notebooks built for data analysis, visualization, and exploration.

This project is an attempt to build re-usable charts and chart components for d3.js without taking away the power that d3.js gives you. This is a very young collection of components, with the goal of keeping these components very customizeable, staying away from your standard cookie cutter solutions.

D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG and CSS.
