The video shows a person drawing a graph on a whiteboard. The person starts by writing the title \"Rainy Levels Over an Aug. Day\" at the top of the board. Then, they draw a horizontal line and label it \"Noon Time\" and \"5:00 pm\" to mark the times of the day. The person then proceeds to draw a series of vertical lines, representing the rainfall levels at different times of the day. The lines are drawn in a way that suggests a pattern of increasing and decreasing rainfall levels throughout the day. The person uses a marker to draw the lines, and the video is shot from a perspective that shows the person's hand and the whiteboard.
