Fixed in 9b58e2dfb2. marimo 0.23.13's _get_binned_fields assumes every vega encoding channel is a dict, but altair compiles tooltip=[...] to a list of field defs — so mo.ui.altair_chart() crashed on these display-only charts. Unwrapped mo.ui.altair_chart(...) to plain chart output in skin_subs_explorer.py and acodb_explorer.py (same latent pattern); nothing read the wrappers' .value, so no interactivity was lost.
