Open source amazes me by the speed of distribution and the power of iteration. Take for example the very fine combination of R and d3 provided here at http://www.biostat.wisc.edu/~kbroman/D3/. The correlation matrix with scatterplot instantly struck me as a wonderful way to liven up Pretty Correlation Map of PIMCO Funds. Since it is open and MIT licensed, within an hour I was able to come up with this.
Please take it and make it even better. Thanks so much to Karl Broman for this great work.
