THe example has hardcoded values inside the Flash application.
The demo is basically showcasing drilldown feature.
If you are using ASP.NET to recreate this, steps are simple:
Create a .NET page (say in URL-A) that responses back XML (for FusionCharts Pie chart) based on a query sent to it (can connect to database etc. in this code)
Create a map in another page using FusionMaps and put link to each state (entity) in the map. The link should call a javascript function pass some unique id (may be of the state)
Create a pie chart using FusionCharts rendered in the page with blank data (ready to be updated when a state in the map is clicked).
The JavaScript function will build a URL-B (URL-A + the id of the state passed as query string)
The JavaScript will pass the URL-B to the pie chart and ask it to update its data from the URL-B.
There is no extra requirement of AJAX and AJAX controls. The chart will internally take care of this.
