Simple Pyramid Chart

This example demonstrates the basic steps in creating pyramid charts.

Create a PyramidChart object using PyramidChart.PyramidChart.
Specify the center and radius of the pie using PyramidChart.setPyramidSize.
Specify the data used to draw the pie using PyramidChart.setData.
Add labels at the center of the pyramid layers using PyramidChart.setCenterLabel
Assign the chart to the WebChartViewer using WebChartViewer.setChart, and insert it to the web page using WebChartViewer.renderHTML. (ASP version)
Generate the chart image using BaseChart.makePicture and assign it to the ChartViewer using ChartViewer.Picture. (VB version)
Generate tool tips for the chart using BaseChart.getHTMLImageMap.
