filter, laterset_filter(), and interactive legends via["all", ...]. Modes:"sequential","cumulative","window". Supports paint-property animation, an optional play button, and a density histogram (d3 loaded on demand).presentation = "timeline"— a prominent, brushable histogram: drag the selected window across the bars, drag its edges to resize.window_behaviorchooses a"resizable"two-edge range or a"fixed"-width band you pan. Modeled on Egor Kotov's FlowMapBlue time control.slider_style()— presets and overrides for the container, play button, track, thumb, and histogram.draggable = TRUE— reposition the panel anywhere on the map, mirroringadd_legend().update_slider_control()(Shiny proxies) andas_time_property().add_flowmap()Animated origin-destination flow maps powered by flowmap.gl (deck.gl): temporal flows, location clustering, customizable color schemes (
flowmap_color_schemes()), CSS blend modes, themeable tooltips/popups. Reactive updates viaset_flowmap_filter()/set_flowmap_settings(); a"window"-mode slider can drive a flowmap's temporal range.

{brace}tooltip/popup templatingAny layer's
tooltip/popup(andset_tooltip()/set_popup()) accepts glue-style templates like"{name}: {population}", alongside the existing column-name andconcat()/number_format()forms. Substituted values are HTML-escaped.tooltip_style()/popup_style()Theme tooltips and popups without hand-written HTML/CSS, mirroring
legend_style()— a preset ("light"/"dark") or custom appearance. Opt-in: tooltips are unstyled by default, so existing maps are unchanged.Co-authored with Egor Kotov (@e-kotov) on the flowmap and time-control work (#205).
