Describe the bug
The graph is entirely empty when no data is available. As Örjan suggests, the graph should be removed if it is entirely empty.

Could you please quickly filter out countries that do not have any of these data for the main classes (Table 1a: Forest; Other wooded land; Table 1b: Naturally regenerating forest; Plantation forest; Other planted forest) to ensure they are not missed?

To Reproduce
Example
