The first module is the sequencer , which is what animates the 500 evolutions and population changes. Import reads the data from the field file created earlier. Rubbersheet warps the representation of the 2 dimensional data to approximate values over the whole image, instead of just plotting single points. The rubbersheet module is what creates the elevation in the images. Colormap allows assignment of colors to specific data values, and hue, saturation, and opacity are controlled here also.
Caption adds and positions text or labels to the image.
The collect module collects all of the above to render the final image from that data file. Camera allows view control, so the image can be viewed at different sizes or depths. The network described above renders only one image in an image window. To view more than one of these images in a single window, the rendered images are collected into one final product and positioned in the image window using the arrange icon. This is done by adding more icons, the Format and WriteImage icons.
