Plot graph reading .csv file
 

I have continuous data being appended to a .csv file. From this I would read the value after every say(10secs) and mark it on the graph.Note that the csv file is continuously updated. In future I wish to display this live graph on my html page. Could anyone suggest the steps I can try.
1. Would I need to install something like gnuplot and then export live graph to html
2. The csv I'm going to read are already displayed through php and html, but that is tabular data, I need a graphical display for the same.

Any help is highly appreciated.
