The logarithmic spiral is plotted with the origin in red It can be expressed in polar coordinates as or parametrically as Each small black point represents the spirals point for a different angle Specifically 80 black points are plotted for each completed round The big black point represents the initial point corresponding to The big blue point highlights the point for the specific angle selected with the control Select fixed axes to restrict the range of in the plot to Without fixed axes the same spiral can be seen resized; the unit line segment along the axis shows the scale
