Draw Eyebrows
Problem Statement:

The pre-placed blocks will draw the ellipse to provide the shape of the face. Add more blocks to draw the eyebrows and the eyes. Use different fill color blocks to change the colors of different features.
```/* Code generated by RoboBlockly v2.0 */
#include <chplot.h>

plot.noStrokeColor();
plot.fillColor("white");
plot.fillOpacity(0.5);

plot.strokeColor("#330000");
// drawing eyebrows: the arc x and y is the center
//  of the circle
// angle is how much of circle you want
// radius determines size of circle
plot.arc(10, 11, 3, 70, 130);
