US Daily COVID-19 Vaccination Dashboard
This dashboard visualizes COVID-19 vaccination data across U.S. states, combining a map with a brushable time-series bar chart. The map displays circular marks positioned via `d3.forceSimulation` with `forceX` and `forceY` to avoid overlaps, sized by vaccination rates. The lower bar chart shows daily doses for a state selected from a dropdown menu, and brushing it updates the map’s date using `d3.brushX`, redrawing circles via SVG with `d3.transition`. Data comes from a CSV of state-level vaccination records, rendered with React, D3 v6, and TopoJSON.
AI-generated descriptionA dashboar showing COVID-19 Vaccination doses administered in the United States. The lower bar chart is the daily number of doses administered in the state selected by the dropdown. The map shows the number of daily doses administered in every state as of the latest data. By brushing the bottom barchart you can select the date for the map to visualize, with the circles representing the number of doses administered in each state on the date at the end of the selected date range.
This barchart has been revised to have non-overlapping circles and to resolve a glitch where circles were appended rather than updated
