Add references/6-custom-visualizations.md documenting the custom-vega-viz widget (Vega-Lite): the serialized widget envelope (stringified jsonSpec, encodings.fields, data.queryName, disaggregated:true, databricks_query data name), container sizing, the SQL-precompute pattern for grids/matrices, and the verified limitation that databricks_mark_selection cross-filtering breaks layered specs. Wire it into the SKILL.md Widget Index and Reference Files tables, and regenerate the plugin bundles. Co-authored-by: Isaac Signed-off-by: Alex Ott <alexey.ott@databricks.com>

What
Adds guidance for building custom visualizations (Vega-Lite /
custom-vega-viz) in AI/BI dashboards — a widget type the skill did not previously cover.skills/databricks-aibi-dashboards/references/6-custom-visualizations.mdSKILL.md: acustom-vega-vizrow in the Widget Index (version 1) and a Reference Files entryplugins/databricks/**bundles +manifest.jsonviascripts/skills.pyWhat the reference covers
custom-vega-vizwidget envelope (the part the public docs omit):version: 1,jsonSpec.specas a stringified Vega-Lite JSON,encodings.fieldsas a flat column list,data.queryName,disaggregated: true, and thedata.name: "databricks_query"literal.containersizing.databricks_mark_selectioncross-filtering breaks layered specs (blank canvas, no error) — single-view only.All content was verified by building and deploying a working custom-viz dashboard (an ATT&CK coverage matrix over a Delta table).
