2. The advantages of this data visualization:
• Easy to understand.
• Show the data in detail.

3. The disadvantages of this data visualization:
• No distinction is made between the colors of the various classifications in the pie chart so that the viewers will feel confuse when see the chart at first eyes.
• There are both positive and negative data in the chart. It seems like there are no specific differences between these two kind of data.
4. My suggestions for improving:
• Add more colors in the chart.
• Turn the pie chart into the column-negative chart which has the distinction of positive and negative data and do not worry about the total percentage.
