Multiple selections

[Shane Carey]

Hi All,

I am new to D3 and I am trying to implement a data selection on a National Map.

I have a Counties Map for Ireland, and when you click on it, it gives you back the data for that county. I want to be able to select 2 counties or multiple counties (by clicking and holding the Ctrl key) and obtain the data for these two counties.

Has anyone got a simple example of how to do this, to get me going?

Thanks in advance!
Cheers
Shane
