The gallery's entry runs natively or, on wasm32, from a wasm_bindgen start
through gpui_web, single-threaded with WebGL2 fallback. ?page, ?story and
?theme choose what shows; an unknown one fails in the page and the log.
set_theme switches the mode later. Pictures load from ELY_GALLERY_ASSETS.
scripts/stories.py writes examples/gallery/stories.json from the pages.
ChoroplethLayer washes each area by its value, keyed by its id or a
property's text or number, on one hue's scale from its faintest at the
least value to its strongest at the most; an area without a value reads
as no data. ChoroplethMap lays it on the owner's map, with or without
tiles, and puts a legend of the scale and of no data in the corner; a
value that matches no area is logged once. WorldMap washes Natural
Earth's 110m countries, bundled trimmed by scripts/countries.py, by ISO
3166 alpha-2 code, and fails on a key that is no code. A shape now
paints as one fill and one edge path per world in view.
MapView takes layers over its tiles and under its pins. RouteLine runs
along places the short way across the date line. read_geojson reads RFC
7946 to features, strictly: a position past the globe, a line of one
position or a ring that does not close fails with its reason, and a
feature placed nowhere keeps no geometry. GeoJsonLayer washes areas as
one path per polygon, so holes stay open, outlines them, strokes lines
and dots points. GeoHeatmap spreads weighted places in a quartic kernel
over small cells, scaled to the densest spot in view. Lines and areas
unwrap across the date line and repeat on every world in view.
cluster_markers gathers pins by squares of the world, so a pan keeps
each group; a cluster shows its count, and its press shows its members
whole, never farther out. A zoom that may regroup them hands a focused
pin's or cluster's focus to the map.
DashboardGrid lays widgets on columns: a tile's strip drags it and its
corner resizes it a cell at a time, others move down and rise to fill
gaps, a focused tile steps with the arrows, and under the theme's
stack_below width the tiles stand in one column. DashboardCard frames a
widget. AlertList acknowledges a firing alert from its row and opens
one on Enter; IncidentCard shows an incident's gravity, phase and
updates. UptimeBar, ServiceStatus and HealthCheck show what is up, a
check's detail wrapping under its name when narrow. EventStream keeps
kinds and holds the list while new events count up.
RefreshIntervalSelector and DashboardFilterBar set the window, the
filters and the refresh. StatCard, MetricsChart, ResourceGauge,
LogStream, TraceWaterfall, SystemMonitor, ProcessTable and NetworkGraph
point to their homes; the maps wait for T41.
