[Teammetrics-discuss] GSoC 2012 : Improving Debian Team Activity Metrics

[Nikhil Bafna]

Hi.

I suggest that graphs be generated on the frontend using js or some js
library. This would be better than generating them on the backend and
displaying the png's.

1. If done on the backend, all the load for generating the graphs for all
user requests fall on the server. If the backend just sends back some data
as JSON for the JS to plot the graph, the heavy work would be distributed
to all user machines.

2. Since the user queries to plot would be dynamic say - "top
N contributors for years X to Y in Z list", the images generated in the
backend couldn't be cached as well. Hence, storing the images will only
take up more space on the server.

3. Sending the image to frontend will take more time than sending data as
json.

Regards,
Nikhil Bafna
