The chart maker draws the numerical value for the categories of a categorical variable.
The online chart may represent the numerical values of the categorical variable as one of the following charts.
The pie chart presents each category as a sector ("pie" slice) in a circle.
The angle of the sector is proportional to the ratio of the category value from the accumulated value.
The bar chart presents each category as a bar, while the height of the bar is the category's value.
The scatter chart, presents each category as a dot, while the height of the dot is the category's value.
The line chart is a scatter chart with a straight line connecting all the dots
First, draw a line chart, then paint all the areas between the line and the axes
