We have updated the applet for transforming densities of points (represented as circles in the dxf file) and areas (as polygons in the dxf file), after the testing last week. Now it should be possible to rotate in windows (hurray!) and to load and save a file from anywhere (so you don't have to copy it into the same folder as the applet). There are also a few other improvements to make it more robust and just a slight change in the visualisation. Hopefully more changes and improvements will be introduced as we test and use it. You can download the new version from here or from the Applets tab on on the right. It does not run properly on the "Datasalen"due to permissions that need to be set by the administrators, but if there is a big demand for this we can ask them to fix it.
