The project involved writing a custom algorithm to convert elevation data into plottable lines, and iterating on the plotter's marker-raising mechanism from a lever arm to a linear design. After plotting the Moon, the project expanded to include contour plots of Mars and Earth. ## Full article daily.dev links to this article rather than hosting it.
