ILINet Flu Surveillance Data Interactive Visualization
This interactive dashboard explores ILINet flu surveillance data from the CDC, showing weekly patient visit percentages across years, states, and regions. Four coordinated panels display temporal trends, a geographical choropleth map, and bar charts ranking state averages. Built with React and D3 v5, the visualization uses d3.scaleBand, d3.scaleLinear, d3.scaleOrdinal, and d3.geoAlbersUsa for rendering, with topojson providing US state boundaries. Users can filter by year and state through linked highlighting and selection, with color legends and tooltips supporting exploration.
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.
