is it possible to add a Tooltip using something like this " getTooltip: ({object}) => { console.log(object) }" - the placeholder console log is showing undefined for the object. I also enabled picking of the layer.

here's a fork where I'm trying this out - https://observablehq.com/@cornhundred/geoarrow-deck-gl-layers-polygon-example-tooltip

I'm thinking this example might help https://github.com/developmentseed/lonboard/blob/b701793e31cf07f4baadb7225a2aaf2b9fe9db75/src/tooltip/index.ts#L24-L66

I got an example working with a tooltip here (https://observablehq.com/@cornhundred/parquet-load-jupyter-embed) but I just need to set up something to look up the data based on the index.

You can look at how we do this in lonboard: https://github.com/developmentseed/lonboard/blob/b701793e31cf07f4baadb7225a2aaf2b9fe9db75/src/tooltip/index.ts

Thanks, I was able to get it working here (https://observablehq.com/d/3599d0a526b29ee1) without using geoarrow/deck.gl/layers but I want to try out the approach you shared as well. In the linked notebook, we're experimenting with loading tiled parquet files when zoomed in using parquet-wasm and displaying them (red dots) - let me know if you have any advice on how to do this efficiently.
