c# - Charting Rectangles of arbitrary dimensions

I need to graph rectangles of different heights and widths in a C# application. The rectangles may or may not overlap.

I thought the System.Windows.Forms.DataVisualization.Charting would have what I need, but every chart type I've explored wants data points composed of a single value in one dimension and multiple values in the other.

I've considered: Box, Bubble, and Range Bar.

It turns out that Richard Eriksson has the closest answer in that the Charting package doesn't contain what I needed. The solution I'm moving forward with is to use a Point chart to manage axes and whatnot, but overload the PostPaint event to effectively draw the rectangles I need on top. The Chart provides value-to-pixel (and vice versa) conversions.
