@d3plus/core

Data visualization made easy. A javascript library that extends the popular D3.js to enable fast and beautiful visualizations.

Installing

If using npm, npm install @d3plus/core. Otherwise, you can download the latest release from GitHub or load from a CDN.

import modules from "@d3plus/core";

In vanilla JavaScript, a d3plus global is exported from the pre-bundled version:

<script src="https://cdn.jsdelivr.net/npm/@d3plus/core@3.0.0-alpha.3"></script>
<script>
  console.log(d3plus);
</script>

Examples

Live examples can be found on d3plus.org, which includes a collection of example visualizations using @d3plus/react.
