Translating Shape Data to the Screen

I just installed Thuban code but am currently having trouble building
it on my Mac OS X (10.3.8)/Darwin. I'm currently setting up
environment variables, etc. so Python (2.4) and PythonWx can see
everything. That said, I need to know which Thuban module actually
translates the ShapLib coordinates into on-screen coordinates.
The following is a piece of a <file>.shp dump:
Shapefile Type: Polygon # of Shapes: 661
File Bounds: (-2168511.500, 417031.562,0,0)
to ( 1492183.500, 2379070.500,0,0)
Shape:0 (Polygon) nVertices=4, nParts=1
Bounds:( -91599.203, 2376631.000, 0, 0)
to ( -89468.781, 2379070.500, 0, 0)
( -91599.203, 2376631.000, 0, 0) Ring
( -90551.562, 2379070.500, 0, 0)
( -89468.781, 2378232.500, 0, 0)
( -91599.203, 2376631.000, 0, 0)
I want to view the code that translates this data to the screen.
Which module actually does this?
Also, any coordination code (and significance) between data from the
.dbf with .shp would be truly appreciated.
Again, Your help would truly be appreciated.
