English: Mathematical "rose" or "rhodonea" curves, based on the polar-coordinates equation r=sin(θ*n/d). In this chart, the values of parameter n varies from 1 to 7, while d varies from 1 to 9.

Based on File:Rose-rhodonea-curve-7x7-chart.svg, which was in turn influenced by File:Rhodonea_curve.png (but with the rows reversed in the layout of the chart).

This graphic converted from the following PostScript vector source code (a slight modification of that used to produce File:Rose-rhodonea-curve-7x7-chart.svg):
