Render a radar chart using d3.

Let's render a chart w/ 4 data points!

var radarchart = require('diy-radarchart');

var target = document.getElementById('passions-chart');

var data = [
    {
        color: '#ccc',
        html: 'Hey there!',
        value: 1
    },
    {
        color: '#999',
        html: 'Hey there darker!',
        value: 3
    },
    {
        color: '#666',
        html: 'Hey there even darker!',
        value: 5
    },
    {
        color: '#333',
        html: 'Hey there the darkest!',
        value: 7
    }
];

radarchart(target, data, { size: 240 });

This would render a radar chart like:

Note that the html is rendered in a .diy-tooltip element after the svg element and is unstyled in this example.

var radarchart = require('diy-radarchart');

Appends a svg element and .diy-tooltip element to $el.

$el is the target element. data should be an array of objects with color, html and value properties.

color is the base color (at 100%) that will generate the various shades for the given segment.

html is the html used to render within the tooltip element.

value should be the relative integer value to all data points that will be used to render the segements within the respective data point.

Sample data point:

{
    color: '#999',
    html: '<span>Hey</span>',
    value: 10
}

The chart can handle any number of data points and value amounts and handles averaging everything.
