I can see the interfase, but whenever I try to upload a file I get the following:
Error: SyntaxError: JSON.parse: unexpected character (2.xls)
BTW, the file "2.xls" is actually "zmbl2.xls", I don't know why it changes the filename.
I've tried this with several files, both .xls and .xlsx, and still get the same error, and the name changing in the error.
Also, why can I only see 3 chart types in the drop-down menu (zoomable treemap, reingold tree, sunburst), when I see the .xls samples for many other chart types??
Also, any chance to display individual charts through shortcode?
