Draw a map

pip install "duckosm[viz]"
duckosm viz monaco.duckdb        # in reports/: monaco_map.html (every mode) + one page per mode

The maps are drawn by mapstyle, duckOSM's map library, from the database itself: water, land, buildings and the sea (base-map layers) under the roads, so the page needs no background from the web (one can still be picked). The roads are coloured by class, with a hover tooltip and a 2D/3D button; click a road to copy its edge_id. Tunnels are drawn under the roads above them, bridges on top. Private roads are grey and bus lanes a muted blue: you see them, but they are not in the network (why). In the Roads box, the road classes and the Bridges, Tunnels, Private roads and Bus lanes rows hide or show those roads.

monaco_map.html has every mode; each monaco_<mode>_network.html brings one mode to the front. Try it: this is Monaco with every mode, as duckosm viz wrote it.

Option	Does
-m driving	only that mode's page (repeat for several); without -m: every mode's page plus <name>_map.html
--basemap voyager	a background from the web under the map: voyager, positron, osm, satellite (default: none, the database's own layers)
--no-arrows	no direction arrows (on by default, on one-way roads; zoom in to see them)
--no-boundary	hide the dashed outline of the area
--out-dir maps	output folder (default reports)

A page holds the whole network, so keep it to a city. For other looks, or to build your own dashboard, use mapstyle directly (pip install mapstyle; its themes, path styles and dashboard page are in its docs).

Other palettes, or colour by a column (needs a clone of the repo):

python scripts/roadstyle_map.py --db monaco.duckdb --palette mono
python scripts/roadstyle_map.py --db monaco.duckdb --color-by maxspeed_kmh

The order in which crossing and meeting roads are painted can be stored in the file: Store the drawing order.
