It can be used to create static charts but more importantly it is designed for building animated data stories

# Vizzu JS Library Reference
2+
3+
This is the API reference documentation of the Vizzu JS library.
4+
The intention of this documentation is to provide information about
5+
every details of the API for user with understanding of the basics of the
6+
Vizzu Library.
7+
8+
For a getting started introduction to the library please visit our
9+
[Tutorial](https://lib.vizzuhq.com/0.3.0).
10+
11+
## Library Overview
12+
13+
The main entry point of the library is the [Vizzu](classes/default.html) class,
14+
and it's most important method controlling the basic functionality of the
15+
library is the [animate()](classes/default.html#animate) method:
16+
17+
* [Vizzu](classes/default.html) class
18+
* [constructor()](classes/default.html#constructor)
19+
* [animate](classes/default.html#animate) ( [AnimTarget](interfaces/AnimTarget.html) , [Anim.Options](interfaces/Anim.Options.html) )
20+
21+
The animate() method's main parameter is the [AnimTarget](interfaces/AnimTarget.html)
22+
interface which contains the definition of the chart, the underlying data and the chart's styling:
23+
24+
* [AnimTarget](interfaces/AnimTarget.html)
25+
* [Data.Set](modules/Data.html#Set)
26+
* [Config.Chart](interfaces/Config.Chart.html)
27+
* [Config.Channels](interfaces/Config.Channels.html)
28+
* [Styles.Chart](interfaces/Styles.Chart.html)
29+
* [Styles.Plot](interfaces/Styles.Plot.html)
30+
* [Styles.Marker](interfaces/Styles.Marker.html)
31+
* [Styles.Axis](interfaces/Styles.Axis.html)
32+
* [Styles.Legend](interfaces/Styles.Legend.html)
33+
* [Styles.Title](interfaces/Styles.Title.html)
34+
* [Styles.Tooltip](interfaces/Styles.Tooltip.html)
35+
36+
37+
## Details:
38+
39+
You can find all interface declarations and types under these namespaces.
40+
41+
### Namespaces:
42+
43+
* [Data](modules/Data.html)
44+
* [Config](modules/Config.html)
45+
* [Style](modules/Styles.html)
46+
* [Anim](modules/Anim.html)
47+
* [Events](modules/Event.html)
