The pie chart icon (top right) is used for switching between visuals. We have a pie chart visual in the same container of scatter chart. Using this button, we may bring any of them to the forward or backward. When pie chart is shown, the button icon changes accordingly.

In the container of pie chart (or scatter chart), bar chart and line chart, we also have table. Table button can be used to switch. When switched, the button icon changes accordingly.
