Draw the flag of Botswana in the center of the canvas. It is 300 units wide and 200 units high.

The flag has five horizontal bands. Divide its height into 24 equal units:

1. Color the top 9 units blue.
2. Add a white band that is 1 unit high.
3. Add a black band that is 4 units high.
4. Add another white band that is 1 unit high.
5. Color the bottom 9 units blue.

Each band stretches across the full width. Do not add outlines or gaps.
