How can I use system.web.ui.datavisualization.charting.chart to make a chart?

Does anyone have a good link for instructions on how to make a basic chart with Microsoft's built-in chart control?

I'd like to make a stacked bar chart, if I could. But, failing that, a regular bar chart would suffice. All the data for the chart is the result of a single SQL call (one result set, 1 label column and 3 data columns, if that makes any difference.)

My google-fu is failing me. Thanks in advance.
