Add/remove nodes from chart Part of PowerCharts XT

The drag node chart is a special type of chart that is rendered using nodes. The existing nodes can be dragged to be edited visually; nodes, connectors, and labels can be added as well as edited. This chart, that uses nodes, shaped as circles, rectangles, or polygons, to represent data sets, is often used to show hierarchies or flowcharts. Connectors are drawn between nodes and text labels are rendered with nodes and connectors to help identify them. Updated positions of nodes can be sent back to the server for processing. This chart is perfect for showing organizational hierarchies, network diagrams, and so on.
