I am attempting to use a "sequence-sunburst" style d3 visualization for some data that I have. To get started, I decided to simply recreate what is given on the d3 website (http://bl.ocks.org/kerryrodden/7090426).
It is here that I have run into some issues:
On line 85 in "sequence.js", I get the following error:
Cannot read property '__data__' of null
Line 85 has the following code:
totalSize = path.node().__data__.value;
Again, to get started, I have copied the js and csv verbatim! I have no idea why this does not work.
Further notes:
- I am using the latest version of Chrome
- I am running Chrome set to
--allow-file-access-from-files - I am opening my html file (also copied verbatim!) using python's SimpleHTTPServer. The port is correctly referenced.
Help appreciated.
