World Map ICE-8_Ganesh
This interactive visualization displays a world map showing the approximate physical locations of students who joined Datavis 2020, with each location marked by a green circle. The map uses the D3 geoNaturalEarth1 projection with geoPath and geoGraticule to render continents, graticules, and interiors. Location data from the Slack introductions is geocoded into latitude and longitude coordinates, and the circles are positioned using the projection function. The visualization follows a React component structure with D3 v5 and renders as SVG.
AI-generated descriptionThis map shows approximate locations of the students who joined Datavis 2020 in its first few days.
The list of locations was compiled by manually going through the places mentioned by students in their introductions in our Slack channel #datavis-2020 in the D3 Slack Group. These are the locations where the students are actually located physically.
Each location mentioned was geocoded using Google (example Kansas City longitude and latitude and entered into the code here in useCities.js.
The locations mentioned range from countries to states to particular cities. For regions like countries or states, the point represents its centroid. Locations are by no means exact, but the point of this viz is to give a sense of the global distribution of students.
