All the noise is just details. The chart is basically three parts:

1: Blue is all the pressures and temperatures where water is solid.

2: Green is all the pressures and temperatures where water is liquid.

3: Yellowish red is all the pressures and temperatures where water is vapour.

I'm not sure what to make of the points and little lines. They seem to have something to do with the ranges within those ranges where the different kinds of ice occur.
