Wrangle Node
Example - Basic Circle of Circle and Phyllotaxis

A circle of points can be created using some very simple code in a point wrangle node.
The vex snippets are similar to C++ code (take VSFX 375).
This is a simple equation of a circle (see Phyllotaxis discussion on cartesian coordinates)
int pts[]; creates an array
for loop structure is the same syntax as C++ code and repeats the statements inside the curly braces (body of the loop) for 0 to less than "total".
total takes its information from the parameter labeled "Total". The parameter was created by clicking the button circled in blue in the above figure.
Taking this one step further, we can create the phyllotactic pattern. Usually I use cos in the x-axis and sin in the y-axis, but either will work.
