ILINet Flu Surveillance Data Interactive Visualization
This interactive visualization presents ILINet flu surveillance data across four linked panels: a line chart of weekly annual averages, a choropleth map of state-level values, a bar chart of top states, and a multi-line trend chart. The d3.js and React-based application uses `geoAlbersUsa` and `geoPath` for map rendering, `scaleBand` and `scaleLinear` for charts, and supports hover/click interactions that highlight selections across panels. The CDC FluView dataset is loaded via `d3.csv` and filtered to exclude non-state regions.
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.
