First, the pie chart did not display information in an elegant visual form with some numbers placed inside the pie while others placed outside. Second, it&#8217;s hard to catch the point of what the visualization wanted to express because we have\u00a0to take time to check\u00a0all the numbers and scan the legend to say that the biggest section is media and the smallest section is electricity. Also, people may be confused with the close colors as such as those light blues. Therefore, this is an inefficient visualization.<\/p>\n<p style=\"text-align: left\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium\" src=\"http:\/\/www.conceptdraw.com\/How-To-Guide\/picture\/Pie-chart-Sector-weightings.png\" alt=\"\" width=\"1110\" height=\"786\" \/><\/p>\n<p style=\"text-align: left\"><em>Reference:\u00a0https:\/\/blogs.oracle.com\/experience\/entry\/countdown_of_top_10_reasons_to_never_ever_use_a_pie_chart<\/em><\/p>\n<p style=\"text-align: left\">\n","protected":false},"excerpt":{"rendered":"<p>An Oracle blog listed 10 reasons that why we should get rid of using pie chart.
