   Datagridxl2.js – Fast Excel-like data table library▲301

   I'm Robbert, the creator of DataGridXL.js. Last month I released version 2 which includes many new features. DataGridXL is a free (and commercial) editable data table library written in ES6. My goal is to develop the most performant & user-friendly spreadsheet-like data table out there: - It has zero dependencies.

It does not even require messing with CSS. - It has its own Virtual DOM implementation to prevent DOM errors. - Developer friendly. Supports all modern web browsers Please take a look at…

    A JavaScript library for data visualization in both SVG and Canvas▲161

    Here's a project I've been working on for a little while now. Ripl is a JS library that provides a unified API for rendering shapes on both canvas and SVG interchangeably. Over the years I've used D3 extensively to create data visualisations so I figured I'd have a go at making my own version with a slightly more modern API and stricter TypeScript support.
