This visualization displays a world map colored by average daily internet usage hours per person, using a blue sequential scale where darker shades indicate higher usage. It renders geographic boundaries with TopoJSON data and `d3.geoPath`, while `d3.scaleSequential` maps values to colors. Countries without data appear gray. Interactive tooltips appear on mouseover showing the country name and hours. The map uses a Natural Earth projection, includes a gradient legend, and animates tooltip transitions via D3’s `transition.style`.
