Vue Charts - Equal Size Pies

To display multiple PieChart components that share series and legend settings, you can use a v-for notation to iterate through every PieChart option.

When you display PieChart components side by side, their pies may differ in size. You can join all charts into a size group to resize these pies to match each other. To do so, set the sizeGroup property of every chart to the same value.
