Title descriptiveness – The title is good and indicates what the figure represents.
Focal points – They do not show the specific waste products on the donut chart, and their percentages are vague (General Authority for Statistics, 2017).
Information sufficiency – The information is not sufficient since not all percentages are shown on the donut chart.
Ease of processing – No ease of processing information.
Takeaway message – All waste products should be indicated alongside their actual percentages.
Figure 2: Bar Graph
Title descriptiveness – The title portrays that the waste products indicated in the bar graph are those significantly used in economic establishments (General Authority for Statistics, 2017). However, it is not clear whether the waste should be the ones released or used.
Focal points – Not clear since the reader will have to guess the amount.
Information sufficiency – Although the information is relevant, it is displayed incorrectly.
Ease of processing – The reader cannot process the data easily since there is no specific order.
Takeaway message – Using bars of different colors can help the reader differentiate wastes used in economic establishments.
2. One of the most effective aspects of the donut chart is the use of different colors for distinctive wastes produced in economic establishments. In addition, a key of what these colors represent is given alongside the donut chart, making it easy for the reader to see waste distribution on the donut chart (Midway, 2020). When it comes to the bar graph, the effective aspect is the labeling of the bars on the x-axis. That way, it is easy for the reader to know the number of different types of waste produced in economic establishments.
3. The donut chart can be improved by showing the percentage of waste produced in economic establishments alongside their actual representation. If the space is limited and cannot accommodate the percentage, an arrow should be used to show the percentage outside the donut chart. In addition, the color of the writings inside the donut chart should be visible. Besides, the bar chart can be improved by labeling the y and x axes. Moreover, the figures showing the quantity of waste released should be simplified. For example, the y-axis should be labeled the quantity of waste produced in economic establishments in “10,000.” In that light, the figures should start from 0, 5, 10…. 40.
