Crate egui_map 

egui-map

An egui widget that renders an interactive 2D map on screen.

The map::Map widget displays a set of nodes connected by lines, with support for:

• Panning (click and drag) and zooming (mouse wheel; hold Ctrl — or Cmd on macOS — to zoom faster).
• Spatial indexing of nodes through a kd-tree, so only the nodes inside the current viewport are painted each frame.
• Node names and free-floating text labels with configurable visibility rules (see map::objects::VisibilitySetting).
• Pulsing notifications and blinking markers attached to nodes.
• Custom node rendering and right-click context menus through the map::objects::NodeTemplate and map::objects::ContextMenuManager traits.
• Independent light and dark themes (see map::objects::MapSettings).

Quick start

use egui_map::map::Map;
use egui_map::map::objects::{MapPoint, RawPoint};
use std::collections::HashMap;

// Build the node set, keyed by node id.
let mut points: HashMap<usize, MapPoint> = HashMap::new();
points.insert(1, MapPoint::new(1, RawPoint::new(0.0, 0.0)));
points.insert(2, MapPoint::new(2, RawPoint::new(100.0, 50.0)));

let mut map = Map::new();
map.add_hashmap_points(points);

// Then, on every frame of your egui update loop:
// ui.add(&mut map);
