gochart's Issues

Rendering the original data into a HTML Table

This gochart tool can rending the original data to a beautiful chart.
I have an ideal : If we can render the original data into a HTML Table and shows it in the same web page, that would be awesome.

Are there anyone interesting to do it?

the binary may be better to put into release page
