The Graphs Panel Controls:
As said before, the Graphs Panel contains two subpanels: 'Visualized' and 'Overall'. Through the Graphs Panel Controls, it's possible to close one or both the panels in order to have more space to look at the map behind.
In this control box, we can see also 3 buttons with the different time granularities, where it's possible to change the x axis of the graphs.
Finally, on the right, we can see 2 more buttons: 'ATL' and 'PAC'. These can be used respectively to change the data that generates the graphs between Atlantic and Pacific hurricanes.
