Vizzu

About The Project

Vizzu is a free, open-source Javascript/C++ library utilizing a generic dataviz engine that generates many types of charts and seamlessly animates between them. It can be used to create static charts but more importantly, it is designed for building animated data stories and interactive explorers as Vizzu enables showing different perspectives of the data that the viewers can easily follow due to the animation.

Main features:

Designed with animation in focus;
Defaults based on data visualization guidelines;
Automatic data aggregation & data filtering;
HTML5 canvas rendering;
Written in C++ compiled to WebAssembly;
Dependency-free.

Installation

Install via npm:

Or use it from CDN:

Usage

Create a placeholder element that will contain the rendered chart:

Create a simple bar chart:

import Vizzu from 'https://cdn.jsdelivr.net/npm/vizzu@latest/dist/vizzu.min.js';

let data = { series: [{ name: 'Foo', values: ['Alice', 'Bob', 'Ted'] }, { name: 'Bar', values: [15, 32, 12] }, { name: 'Baz', values: [5, 3, 2] }] };

let chart = new Vizzu('myVizzu', { data });

chart.animate({ x: 'Foo', y: 'Bar' });

Then turn it into a scatter plot:

chart.animate({ color: 'Foo', x: 'Baz', geometry: 'circle' });

Try it!
