AI Drawing Prompt Reference

Create a chart showing the relationship between a pie chart and a dot plot. Generate five random numbers and represent this data with a dot plot. Draw a circle with one point as the center and place six points evenly on the circle. Use these points to create six sectors, each representing a part of the pie chart. Measure the central angles of each sector and calculate the corresponding arcs. Determine the exact boundaries of the sectors by finding the intersections of angle bisectors with the arcs. Finally, adjust the sizes of the sectors based on the dot plot data to make the pie chart accurately reflect the distribution.
