Unable to get property ‘update’ of undefined or null reference
weightedtree_test.js (253,5)I thought that ‘weighted tree’ was excellent api for visualization of my data, so I just tried to use ‘weighted tree’. I modifed the cvs data file inside of the data folder and applied it to the html file, but I found it unavailable. The console window showed the sentences above, please help me to fix and use it for my research.

I would recommend downloading the test file again and making sure it runs correctly before you have made any modifications to it.
Once you have done that, I would then make your changes in small increments to see where things have broken.
It appears you may be missing a reference to a javascript file, which can sometimes happen if you re-organize the folder structure or put your HTML test page in a different location. In that case be sure to update the paths to all javascript file references.
