I am looking for a software tool that allows to create maps which can be customized by the user later on. To be more concrete: the user should be able to choose different indicators, create his own aggregate scores, attach weight to the indicators and so on. One example is the OECD better life index, it contains these features (you can choose which indicators you want to include, you can weight them, etc). Do you know such a visualization program? The well known ones like Geocommons, ArcGIS, Spatialkey, etc. do not have these features.
Thanks a lot for your help,
