This dashboard visualizes COVID-19 vaccination doses administered across the United States, combining a choropleth-style map with a linked bar chart. The map displays circles representing vaccination numbers for each state as of a selected date, while the lower bar chart shows the daily doses for a state selected via a dropdown menu. Users can brush the bar chart to choose a date range, updating the map accordingly. The visualization is built with React and D3 v6, using `d3.geoPath` for the map, `d3.forceSimulation` for circle packing, and `d3.brushX` for brushing interactions.

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
