This interactive dashboard presents U.S. influenza surveillance data from the CDC’s ILINet dataset, combining four linked panels: a yearly line chart, a choropleth map of state averages, a ranked bar chart of top states, and a state-conditional line chart. Users can select years and states to highlight across views, with hover interactions revealing tooltips. The visualization is built with React and D3 v5, using `d3.scaleBand`, `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.scaleSequential`, `geoAlbersUsa` for map projection, and `d3.csv` for data loading, rendering all marks as SVG.
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.
