ILINet Flu Surveillance Data Interactive Visualization
This interactive dashboard presents ILINet flu surveillance data across four coordinated views: a line chart tracking weekly trends by year, a choropleth map showing the geographical distribution across US states, a bar chart ranking the top states, and a detailed line chart for selected states. Built with React and D3.js v5, the visualization uses `d3.scaleOrdinal` for color encoding, `d3.geoPath` for map rendering with a Natural Earth projection, and `d3.curveCardinal` for smoothed trend lines. The data comes from the CDC FluView Interactive dataset, processed through TopoJSON for geographic boundaries.
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.
