You can develop your canvas in the PowerPoint attached to collect the information from a group.
Or you can develop the canvas in Wovex to start your map where you will continue to develop it.
There is a Canvas background template in Wovex (as below) so you can start developing your initial Benefits Map in Wovex.
Go to File > New > and open a "2. Blank Wovex Canvas" template.
Start your own map on top of the background image of the canvas and then you can delete the canvas image and develop your map from there.
