Analyze eye tracking data

Hi,

I am a newbie in eye tracking field and want to know the way to analyze and visualize obtained data.

The data I have is just x-y coordinates with more than 2000 points and want to visualize its trace and draw a heat map. (Any other ways to visualize and analyze the data are fine)

Is there any toolbox or function which help me to do those kind of things?

Thank you very much.
