New Legend Layout For GDELT Summary

As GDELT Summary's visuals are increasingly used as-is, rather than rerendered in R, Excel or other statistics packages, we've gotten a lot of feedback that the optional right-hand vertical legend would be better as an always-on horizontal legend beneath the timeline graphs. This is especially important for Comparison graphs, where the legends can occupy considerable horizontal space when exported as static images.

We've updated GDELT Summary's timeline displays to place the legends at the bottom of each graph in horizontal format (the items automatically stack vertically as needed in space-constrained displays) and make them always visible.

Based on feedback we've also adjusted the X axis time labels to always display vertically when exporting as a static image in order to make them more consistent with the visuals produced by common statistics packages.

We hope these new visual updates, while subtle, make the graphs even easier to use!
