dot_map.rotate in orthographic mode: lng is rotation about the
pole (the sub-observer meridian), lat tilts which parallel faces the
camera. Both default to 0 (looking at (0, 0)).
A great-circle arc lifted off the globe’s surface, drawn between two
[lat, lng] endpoints. draw_in reveals the arc from from towards
to (1.0 = fully drawn) as a per-arc ceiling: the fraction actually
painted this frame is draw_in scaled by the node’s own animated
draw_progress when one is active (the same property line/arrow
read), so a draw_progress keyframe on the dot_map component now
sweeps every arc in over time instead of being silently inert. With no
draw_progress animation, draw_in alone still applies as a fixed
fraction.
dot_map.projection. Equirectangular is the historical flat mapping
(lng/lat scaled linearly onto the box); Orthographic renders the map
as a globe seen from outside, with the far hemisphere culled and dots
converging towards the limb — a clip-path: circle on the flat map only
cuts a disc out of it, it never curves.
A rotate.lng value: either a fixed longitude, or a linear sweep from
from to to starting at the component’s own start_at, over
duration seconds (defaults to animation_duration).
