This interactive dashboard visualizes CDC ILINet flu surveillance data across four synchronized panels: a yearly line chart, a choropleth map of state averages, a bar chart of top states, and a focused line chart for selected states. Built with React and D3 v5, it uses d3.scaleBand, d3.scaleLinear, d3.scaleOrdinal, and d3.scaleSequential for scales, along with d3.geoAlbersUsa and d3.geoPath for map rendering. Hovering or clicking a year updates the map, while state selections highlight corresponding bars and curves.
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.
