This interactive dashboard visualizes CDC ILINet flu surveillance data across four coordinated panels: a line chart showing weekly patient visit percentages by year, a choropleth map of state-level averages, a bar chart ranking top states, and a line chart tracking those states' trends. Built with React and D3 v5, the visualization uses `d3.scaleBand`, `d3.scaleLinear`, `d3.geoAlbersUsa` with `d3.geoPath`, and `d3.line` with `curveCardinal` for smooth paths. User interactions like hovering and clicking filter and highlight linked selections across all panels.
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.
