This dashboard presents a four-panel visualization of CDC ILINet flu surveillance data, showing weekly patient visit metrics across years and US states. It includes a line chart of annual trends, a choropleth map of state averages, a bar chart of top states, and a colored line chart tracking those states over time. Built with React and D3 v5, the example uses `scaleOrdinal` for color mapping, `geoAlbersUsa` and `geoPath` for map rendering, and `scaleBand`/`scaleLinear` for bar and line axes. Data is loaded via `d3.csv` and `d3.json`, with interaction implemented through React state and D3 event handlers.
AI-generated descriptionThis project use D3.js and React to display an interactive four-panel view for visualization. The Data used is the ILINet Flu Surveillance Dataset from ILINet Flu Surveillance Report. The original data is downloaded from the webpage: CDC FluView Interactive.
Four Panel View The visualization is composed of 4 panels.
- The first line plot displays annual average patient visits percentage or other values from the dataset on weekly bases. It demonstrates the pattern for different years.
- The second plot is a choropleths map shows the geographical distribution over the US including Alaska and Hawaii.
- The third plot is a bar chart shows the top 10 or N states. It gives the user more quantitative information and a list of top states by name.
- The fourth plot to show the yearly trending pattern of these states using a colorful line chart, using the same color scheme used by bar chart for different states.
