ILINet Flu Surveillance Data Interactive Visualization
This interactive visualization presents influenza surveillance data from the CDC's ILINet dataset across four linked panels. A line chart displays annual trends in patient visit percentages by week, a choropleth map shows the geographical distribution of average values across US states, a horizontal bar chart ranks the top N states by value, and a multi-line chart reveals yearly patterns for those selected states. Built with React and D3.js v5, the visualization uses `geoAlbersUsa` for map projection, `scaleBand` and `scaleLinear` for bar and line charts, and `scaleSequential` with `interpolateYlOrRd` for the map's color encoding.
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.
