ILINet Flu Surveillance Data Interactive Visualization
This interactive visualization explores ILINet flu surveillance data through four coordinated panels. A line chart shows weekly trends across different years, a choropleth map displays the geographical distribution of values, a bar chart ranks the top states, and a colorful line chart reveals the yearly patterns for those selected states. The code uses D3.js for creating SVG marks, including `scaleBand`, `scaleLinear`, `scaleOrdinal`, and `scaleTime`, along with `geoAlbersUsa` for map projections. React manages user interactions such as hovering and selection, while TopoJSON provides the US state 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.
