panel-mosaic¶

Interactive, DuckDB-powered Mosaic visualizations for Panel.

panel-mosaic lets Panel applications render declarative Mosaic and vgplot charts. It keeps data in DuckDB and sends only the result of each browser-side query to the chart, making it a strong fit for linked views and large datasets.

Start here¶

pip install panel-mosaic-viz

Create a Mosaic pane with a chart specification and a DuckDB connection:

import duckdb

from panel_mosaic import Mosaic

con = duckdb.connect()
con.execute("CREATE TABLE points AS SELECT 1 AS x, 2 AS y")

Mosaic(
    {"plot": [{"mark": "dot", "data": {"from": "points"}, "x": "x", "y": "y"}]},
    con=con,
)
