### Drawing square triangulations

The story so far:

I introduced the tabular method by showing how to count the triangulations of a convex polygon;

I used the tabular method to count the number of ways to triangulate an oriented

*n*×*n*square using only lines joining the 4*n*integer points around the edge of the square and so solve Project Euler problem 270;I used the

`svgwrite`

Python package to draw the triangulations of a convex polygon using Scalable Vector Graphics; andI read Appendix J of the SVG specification and used the advice therein to shrink the size of the generated SVG.
