 XChart is a light-weight and convenient library for plotting data designed to go from data to chart in the least amount of time possible and to take the guess-work out of customizing the chart style.
 
-Usage is very simple: Create a `Chart` instance, add a series of data to it, and either save it or display it.

-All the styling options can be found in one of two possible places: 1) the Chart's `StyleManager` or 2) the series' `set` methods.

+## Chart Types
+
+Currently, there are three major chart types: `Chart_XY`, `Chart_Category` and `Chart_Pie`. Each type has its corresponding `ChartBuilder`, `Styler` and `Series`.
+
+| Chart Type | Builder | Styler | Series | Allowed X-Axis Data Types | Default Series Render Style |
+|---|---|---|---|---|---|
+| Chart_XY | ChartBuilder_XY | Styler_XY | Series_XY | Number, Date | Line |
+| Chart_Category | ChartBuilder_Category | Styler_Category | Series_Category | Number, Date, String | Bar |
+| Chart_Pie | ChartBuilder_Pie | Styler_Pie | Series_Pie | String | Pie |
+
+The different Stylers contain chart styling methods specific to the corresponding chart type as well as common styling methods common across all chart types.
+
+### Chart_XY
+
+`Chart_XY` charts take Date or Number data types for the X-Axis and Number data types for the Y-Axis. For both axes, the tick marks are auto generated to span the range and domain of the data in evenly-spaced intervals. 
+
+Series render styles include: `Line`, `Scatter` and `Area`.
+
+### Chart_Category 
+
+`Chart_Category` charts take Date, Number or String data types for the X-Axis and Number data types for the Y-Axis. For the X-Axis, each category is given its own tick mark.  
+
+Series render styles include: `Bar`, `Line`, `Scatter`, `Area` and `Stick`.
+
+### Chart_Pie
+
+`Chart_Pie` charts take String data types for the pie slice name and Number data types for the pie slice value.  
+
+Series render styles include: `Pie` and in the near future `Donut`.
