# 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](https://www.npmjs.com/package/vizzu):
```sh
npm install vizzu
```
Or use it from CDN:
```html
```
## Usage
Create a placeholder element that will contain the rendered chart:
```html
```
Create a simple bar chart:
```javascript
import Vizzu from 'https://cdn.jsdelivr.net/npm/vizzu@0.17/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
});
```
```javascript
chart.animate({
x: 'Foo',
y: 'Bar'
});
```
Then turn it into a scatter plot:
```javascript
chart.animate({
color: 'Foo',
x: 'Baz',
geometry: 'circle'
});
```
