Working Title
This interactive visualization presents the CDC's ILINet flu surveillance data through four coordinated panels. A line chart shows annual trends, a choropleth map displays geographic distribution, a bar chart ranks top states, and a second line chart highlights selected states’ yearly patterns. Built with React and D3 v5, it uses `d3.scaleBand`, `d3.scaleLinear`, and `d3.scaleOrdinal` for chart scales, `d3.geoAlbersUsa` and `d3.geoPath` for the map, and `d3.curveCardinal` for smoothed lines. User interactions include hovering and clicking to filter data across panels, with opacity changes to emphasize selections.
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.
