text position and repel on map

Hi,

Thanks for developing Altair! Finally a great tool for visualization using the grammar of graphics in python! I am really having a lot of fun with it!

I am visualizing a map using mark_geoshape. I am adding points to the map using mark_point, and corresponding labeling text using mark_text. I have two issues:

1. The text is not always close to the corresponding point. I use x = "longitude:Q", y = "latitude:Q" both in mark_point and mark_text. As an example, see the distance between the green dot and the green text in the figure attached;
2. Texts often overlap - see the pink and brown texts in the figure attached. Is there any function similar to ggrepel in ggplot?

Thank you very much again for such a great tool! Serena

It has been implemented and we are in the process of releasing the feature in Vega. The code is already in master at https://github.com/vega/vega/tree/master/packages/vega-label. Once we have support in Vega, we can support it in Vega-Lite as well. I can’t promise a release date yet but it’s coming. Thanks for your patience. It’s a big feature to add with a lot of moving parts.

Yes and yes. We are working on getting it into Vega and then Vega-Lite. I can’t promise a release date yet, though.
