Creates SVG based, animated bar, pie, donut and line charts out of your CSV data. A powerful, easy to use shortcode.

== Description ==

IPU-Chart is an easy to use shortcode that creates SVG based bar, pie, donut and line charts out of your CSV data.

The plugin takes a csv file (Texteditor, Excel, Numbers etc.) and displays it as a chart. IPU-Chart is based on [SVG](http://www.w3.org/TR/SVG/) and [D3](http://d3js.org/). It works perfectly on large computer screens as well as on tablets and smaller mobile screens. For browsers that do not support SVG an alternative image can be set.

= Features =

* Create bar, pie, donut and line charts
* Enter the csv data directy in you blog or page
* Or load the csv data from a remote location
* Create multiple views of the csv data
* Tooltip for chart details (see screenshots)
* Animated bar charts
* Define colors and number formats of the chart
* Create an additional table view of the csv data

= Usage =

First, define your data. You can create it immediately in WordPress or copy and paste it from an export of your favourite spreadsheet application.

<pre>
[csv id='popdata']Country,Population
China,1343.24
India,1205.07
United States,313.85
Indonesia,248.22
Brazil,205.72[/csv]
</pre>

Second, define the chart. Reference the csv (don't forget the '#'). Set the chart type and the category and value column. Define the format (string, integer, float or date) of the category and value columns.

<pre>
[chart id='chart0' 
       csv='#popdata' 
       type='bar | bar.horizontal | pie | donut | line'
       category='Country'
       value='Population'
       format='sting,float'
       color='DarkOrange, DarkBlue'
       style='height: 350px'
       title='Top five most populous countries of the world...'
       description='The top five most populous countries of the world...'
       sort='Population'
       interpolate='cardinal'
       animate='medium'
       img='http://www.example.com/chart0.png'
       debug='false']
</pre>

To define a table view just reference the csv (don't forget the '#'):

<pre>
[table id='table0' 
       csv='#popdata'
       debug='false']
</pre>
