Scale problem on the map #95

With the Endangered Languages data, we have a huge range of values when sum of no of speakers is calculated for each point. As a result numbers from 6 up to 600,000 look like the same size dot.

One option for investigating this is to include a histogram (like the timeline) that shows the range (on a logarithmic scale. Or that we give the option to bin the numbers into a 5 or 6 levels of scale instead of trying to represent every value. This would at least show order of magnitude.

Can we add another dimension to the data set that is a log-scale transformation of the "No of speakers" value. "log(No of speakers)"? And use that for the visualization? That should help quite a bit at the moment.

I agree we need to beef up Palladio's data transformation capabilities. Various transformations of numeric dimensions should be among the capabilities.

I actually tried this and something is going screwy so that I can't assign a tooltip on the map correctly. Need to look into it...
