Consider whether similar datasets can be combined into shared cards, on area page

From @juliacush in #568:

Can support (offshore wind / onshore wind / etc) data be made into one bar chart?

As we add more datasets to the Hub, the information density and navigability of the area page continues to be a challenge.

Perhaps one partial solution might be to (re-)combine the cards for multiple similar datasets, like the renewable energy generation public opinion data @juliacush mentioned above.
