I would like to display a pie chart in a custom SharePoint application page. One option to do this is by using MSCharts and
<asp:Chart> tag. However, getting this to work requires modification of web.config. Because I would like my app to be easily deployable to different environments (across farms and web applications), I'd prefer not having to edit web.config to get charts to work, as this requires tedious extra work to avoid potential production problems (as far as I know - is there an easy automatic way to solve this?).
Are there any other (ideally out of the box) charting options that I can use in a robust, easy-to-deploy way, i.e. I'd like to minimize the chance of production environment problems due to e.g. invalid web.config?
Ideally, I'd like to avoid scripts and would have total C# control over the displayed data.
