This interactive globe visualization displays cities with populations over 100,000 as circles sized by population, projected onto an orthographic globe that supports panning, zooming, and rotation. Using d3.geoPath with d3.geoOrthographic, it renders country boundaries from the world-110m and world-50m TopoJSON datasets, switching to lower-resolution shapes during drag interactions for performance. City data originates from preprocessed Geonames data, with tooltips provided via d3-tip and interaction handled through d3.drag and d3.zoom.

AI-generated description

A globe with pan & zoom showing circles for each city of over 100,000 inhabitants. Data from Geonames, preprocessed. The same data is used in World City Explorer.

Uses world-110m and world-50m geographic shapes from TOPOJSON World Atlas.

Second Iteration of project

This interactive globe visualization displays geographic data points overlaid on a world map, allowing users to pan and zoom through drag and scroll interactions. Built with D3.js, it uses a geoOrthographic projection to render country boundaries from TopoJSON data and circles for coordinates, with a visibility tester streaming projection checks to display only points on the visible hemisphere. The code leverages D3’s drag and zoom behaviors to update rotation and scale state, enabling smooth navigation. The underlying dataset is dummy data with latitude and longitude columns, rendered as red circles for each unique coordinate pair.

Fork of Cities on a Globe

This visualization presents an interactive orthographic globe displaying circles for cities with populations exceeding 100,000, sourced from preprocessed Geonames data. Users can pan and zoom the globe using drag gestures and the mouse wheel, with low-resolution country boundaries shown during movement and high-resolution shapes rendered when stopped. The code leverages d3.geoOrthographic, d3.geoPath, topojson, and d3-tip for hover tooltips, while a square-root scale maps population to circle radius. Hovering over a city reveals its name and population in a formatted tooltip.

Cities on a Globe

This interactive globe visualizes cities with populations over 100,000 using circles sized by population. Users can pan and zoom the orthographic projection. The visualization renders country borders from world-atlas TopoJSON data and city coordinates from a Geonames CSV file. It leverages d3.geoOrthographic, d3.geoPath, d3.scaleSqrt, and d3-tip for tooltips, with d3.drag and d3.zoom handling interaction.

Fork of Final version - Globe

This interactive globe displays cities with populations over 100,000 as circles, using pan and zoom to explore geographic distribution. Hovering over a point reveals a tooltip table listing cricket match details from the linked dataset, including teams and winning outcomes. Built with D3.js, it uses `d3.geoOrthographic` projection and `d3.geoPath` for landmasses, with city coordinates plotted from GeoNames data. The visualization incorporates SVG rendering and custom tooltip positioning to handle viewport constraints.

Fork of Cities on a Globe

This interactive visualization shows a globe displaying circles for cities with populations over 100,000, using data from Geonames. Users can pan and zoom the orthographic projection, with low-resolution world boundaries shown during movement and higher-resolution boundaries when settled. The globe is rendered using d3.geoPath with a d3.geoOrthographic projection, while city positions are computed and projected onto the SVG. d3.drag handles rotation, and d3.zoom manages scaling. Hovering over a city reveals a tooltip, implemented with d3-tip, showing the city name and formatted population. Data includes country outlines from the world-atlas TOPOJSON files and city coordinates from a preprocessed CSV.

Fork of Cities on a Globe

This interactive globe displays cities with populations over 100,000 as pink circles, with size scaled by population and hover tooltips showing city names and populations. Users can drag to rotate the globe and zoom to adjust the scale, switching between 110m and 50m resolution world boundaries during interaction. Built with D3 v4, it uses `d3.geoOrthographic` for projection, `d3.geoPath` for rendering country shapes, `d3.drag` and `d3.zoom` for interaction, and `d3-tip` for tooltips. City data comes from a preprocessed GeoNames CSV, while country geometries use TopoJSON from the world-atlas package.

Fork of Cities on a Globe

This interactive globe displays over 100,000 cities as circles sized by population, with hover tooltips showing names and population counts. Users can pan by dragging and zoom via scroll or pinch gestures, swapping between 110m and 50m resolution land boundaries during motion for performance. The visualization uses d3.geoOrthographic for projection, d3.geoPath for rendering, d3.drag and d3.zoom for interaction, and d3-tip for tooltips. City data comes from a preprocessed GeoNames CSV, while geographic shapes use TopoJSON world-atlas data.

Fork of Cities on a Globe

This visualization displays a three-dimensional globe with colored circles marking cities with populations over 100,000, drawn from preprocessed Geonames data. Users can drag to rotate the Earth and scroll to zoom, with smooth transitions between low- and high-resolution country boundaries from the TopoJSON World Atlas. The code uses d3.geoOrthographic for projection, d3.geoPath to render geographic features, and d3.drag with d3.zoom for interaction. Circle sizes scale with population using d3.scaleSqrt, and hovering reveals a city’s name and population via d3-tip tooltips.
