Question

Difference between column chart and pie chart
​

Answer 1

Explanation:

A bar chart, or bar graph, is a very common two-dimensional data visualization made up of rectangular bars, each corresponding to a category and whose length represents the value of that category. The bars can be either vertical (sometimes called a column graph) or horizontal. For example, this figure shows a bar chart of the results of the 2000 US presidential election. Each bar represents a candidate (the category) and the height of the bar represents how many votes that candidate received (the value).

figure 1

Here are the same election results, but presented with a horizontal bar graph.

figure 2

A pie chart is also a very common two-dimensional data visualization where categories and their values are represented. But in this case the values are proportions of a total and they are visualized as slices of a circle (a pie). Here are the same results on the 2000 US presidential election represented as a pie chart.

Note that instead of showing the count of votes as the value of interest, as in the bar charts, the pie chart focuses on the percent of the total votes.
