Hi Brendon,

We'll look at implementing the buffer area. The trouble with this is that if the bounds of the data are the very edge of the world you'd end up with white chunks of nothing around the chart area. In the past we've used "dummy" points with values of zero to pad out the visible area for a GIS chart. Looking at your dataset this may not be feasible.

If you change the hyperlink field for the drill to the field containing the geometry data you will get links on the bubbles.
