Python 2.7: some drawing work then save to image file?

Question

I am new to Python and need some help.

I need to read data from a file, say some (x, y) data, then plot them and draw some lines, as well as some text output, on a X-Y coordinate system. Then I need to save the image to a file (PNG, JPG or BMP, don't care about format).

Can somebody give some suggestion/directions? Thanks a lot.

Thank you all for the help. I finally finish my work using these functions:

import matplotlib.pyplot as plt

import htmltag

import csv

plt.clf()

...

plt.savefig

...

reader = csv.DictReader(csvfile)

...

output = open("a.html","w")

output.write(text)

output.close()
