I have prepared the testing implementation of Rickshaw wrapped into a 
general linechart and connected it to Ceilometer here:
(rendering is mostly copied from examples with some parts from Maxime 

Rickshaw really works like a charm. I think it will be the best choice.

It is work in the progress and the data of the statistics needs to be 
formatted correctly, but it shows this could work.

I will extract the parts to correct Blueprints and I will start the 
blueprints for implementation of the charts in the dashboard, then 
connect it through dependencies. So people can start implementing this 
to dashboard.

There is ongoing UX discussion about the ceilometer and the charts in 
the dashboard and how it will look like. I do expect we will use 
scatterplot, pie and bar charts (we are using this on overview pages in 
tuskar-ui). So these charts should be probably packed in similar manner 
(though only scatterplot is in the Rickshaw)
