Hi Md A.,
What I have so far is at [url removed, login to view] There are two D3 charts there which I created by customizing sample code. I have been able to figure out most customizations but am still struggling with finalizing it.
Some things I have tried to do without success:
1. customize the styles of the tooltips that pop up (hover over "Technology"). For example I want to set a max-width and change the background color, and maybe add rounded corners. Trying to add a CSS style for .tooltip did not work.
2. Attach text elements to the bottom chart rectangles, similar to those in the top chart. Text labels are already in examplegantt.js.
3. Animate the bottom chart, with bars growing from the left.
Is this something you can help with? Please accept only if you have the expertise and the time to help me over the next few days.
