Hello, I am trying to get started with Highcharts using Visual Studio, I am using VB and SQL and ASP.net

I found lots of php examples, but really need an example using the criteria above. Does anyone have an example of this. I think I would need to use a JSON file as well.

any help would be much appreciated

here is a old page I used to get started.

chartDev.aspx
