This interactive globe visualizes major world cities using an orthographic projection, with labels that dynamically appear as users drag to rotate and scroll to zoom. Canvas handles the geographic rendering of countries, graticule, and sphere gradient via `d3.geoOrthographic` and `d3.geoPath`, while an SVG overlay draws city labels using collision detection powered by `rbush`. Population data from a CSV file is filtered and scaled with `d3.scaleSqrt`, with interactive controls implemented through D3’s `drag` and `zoom` behaviors.
