One of my readers asked that what software I use to create my asset allocation treemaps. Unfortunately, I am using my own custom software to track my assets and investments, however the script that builds this particular graph is made by HighCharts. So I decided to make a small script to allow others also to create these graphs easily. It only needs some manual input. I know many use excel so creating input for this script should not be very hard.
Anyway the link to the script is here: https://rawgit.com/ilves/visualisation/master/index.htm
I did not spend much time on it, so there could be some bugs or limitations. If anyone finds one or have some ideas how to improve it or have any questions/problems please let me know!
