I have a vector dataset with monthly water risk data per river basin. The data is available for each month (January - December) and I would like to visualize this in a browser. The geometries are constant (river basins do not change).
The data is structured as two files: a shapefile with unique identifiers and a .csv file with the unique identifiers, month and value.
The preferred way to display one month of data is using choropleths. I think a very powerful way to visualize the temporal component is to have a time slide and "play" button.
