I need to insert a horizontal bar chart in a web page. The thing I have to do is very similar to a Gantt Chart.
I'd like to use a javascript library for the purpose. I tried jsgantt, but actually it is not very beautiful.
I could evaluate also a server generation of the graph. In case my server side language is Python.
It will be part of an internal project with no internet access, so Google Charts isn't an option.
Have a look at the flot jQuery plugin:
Flot is a pure Javascript plotting library for jQuery. It produces graphical plots of arbitrary datasets on-the-fly client-side.
The focus is on simple usage (all settings are optional), attractive looks and interactive features like zooming and mouse tracking.
The library can produce bar graphs, and is used by our host site - have a look at Stack Overflow Reputation History page.
