plotting data from a csv file on a basemap

Hi!

I am farely new to matplotlib and basemap. I have one question about how to plot data from a csv file on a map.

the header goes as this

ID lat(x) long(y) measurements(z)

how can I read data in that
x gets the latitude
y gets the longgitute
z gets the data which will be shown in different color accoring to their values?

I played around and started from quiver_demo.py but didn't find my way.

reader = csv.reader(open('t.csv'))
for row in reader:
    print row

Could you give me some hints or starting points?

Thanks,
Tim

Use pylab.load to load the data into an array. Then, the rest of what
you want to accomplish is detailed in the wiki:

Hope that helps!
