Sparkline PHP Graphing Library

Aren’t there existing PHP graphing packages that will generate sparklines? Why write your own?
In theory, any PHP graphing package should be able to generate a sparkline. In practice, however, many of these libraries are written with assumptions about the size of graphs they’re going to produce. Simple rules about how to space tick marks on axes and what amount of padding belongs around graph elements begin to break down when the entire graph is 100×15 pixels.
