## Lesson goal: Do some computerized drawing

Previous: Drawing with text | Home | Next: The Cartesian Coordinate System

After you can draw pixels, lines, and circles, why don't you see if you can put them together and draw something? How about a stick figure? Car? House?

To get this to work, you have to visualize your drawing in terms of $(x,y)$ points on the grid, with $(0,0)$ at the center. You can move the mouse pointer over the plotting area (to map out needed $(x,y)$ points) as you create your work. Have fun!
