West Nile Virus (simplified)

US State Map

This interactive US state map visualizes West Nile virus case data from the provided CSV, using a choropleth color scale where each state’s fill color encodes total reported cases. Hovering over a state highlights it and displays a tooltip with the state name and its case count. The visualization uses D3 v3 and SVG paths to render state boundaries, with hover effects that reduce fill opacity for emphasis. The tooltip is a styled HTML div that appears near the cursor, showing the state name and total cases in a clean table format. The map is accompanied by a legend-less color scale interpolating from light yellow to dark blue, and includes animated transitions for interactive feedback. Data for the map is derived from the provided West Nile virus case counts by state, and the visualization is built by adapting an existing block with the same name. The map is embedded in an HTML page with a full-screen SVG and uses custom JavaScript to bind the data to the state paths.

US State Map

This map visualizes West Nile virus cases across US states, with each state colored by a randomized metric (low, average, or high case counts) rather than the actual case data. The choropleth uses an interpolated teal-to-purple color scale, and hovering over a state triggers a tooltip displaying the state name along with its low, average, and high case values. The map is rendered as an SVG with a click/touch interaction, and state boundaries are drawn with thin gray strokes. The visualization is built with D3 v3 and includes animation capabilities. Data is loaded from a CSV file listing neuroinvasive and non-neuroinvasive disease cases per state, though the visual mapping shown uses random sample data rather than the actual values.

US State Map

This interactive map visualizes West Nile virus cases across US states, with each state colored according to a metric and displaying a tooltip with case counts on hover. The choropleth uses a custom color scale interpolating from light yellow to cyan, mapped to state-level case data loaded from a CSV. Hovering over a state highlights it and triggers a tooltip showing the state name and its total number of cases. The map is rendered using SVG paths from the uStates.js library, with smooth color transitions and hover effects provided by D3 v3.

Virus chloropleth West Nile 2015

This choropleth map displays total West Nile virus cases per U.S. state for 2015, color-coded on a logarithmic scale from cyan to black. Hovering over a state reveals a tooltip with its name and case count. The visualization loads data from a CSV, merges it with GeoJSON state boundaries, and renders SVG paths using d3.geo.path with an AlbersUSA projection. The code also includes paths for hover effects and a legend.

Virus chloropleth

This map shows state-level surveillance data for West Nile virus and Zika virus infections across the United States. It uses a color-coded choropleth to distinguish total case counts per state, with tooltips revealing detailed figures for neuroinvasive and non-neuroinvasive disease cases, deaths, and presumptive viremic blood donors. Built with D3 v3 and rendered as SVG, the visualization encodes magnitude through graduated fill colors. Users can toggle between datasets for West Nile virus (2015 and 2016) and Zika virus (2015). The map was adapted from prior blocks by Michelle Chandra, Scott Murray, and others, with sources and code publicly available. It serves as an educational resource for the "Bugs to Barcodes" project at James Madison University.

US State Map

This interactive map displays the geographic distribution of West Nile virus cases across the United States. State boundaries are drawn using SVG paths provided in the `uStates.js` file. The visualization uses D3.js v3 for data binding and rendering, with a tooltip that reveals low, average, and high case values from the `WestNile.csv` dataset on hover. The map supports color-coded choropleth styling and includes animated transitions for state highlighting.

US State Map

This interactive US State Map visualizes West Nile virus case data across the United States, with each state colored according to randomly generated statistics for low, average, and high case counts. The choropleth map uses a yellow-to-dark-red color scale, where darker shades indicate higher case numbers. Users can hover over any state to see a tooltip displaying the state name alongside its low, average, and high values. The map is rendered using D3.js with SVG, and the tooltip provides a clean, readable breakdown of the data, with states highlighted on hover for enhanced interactivity.

Virus chloropleth west nile 2016

This choropleth maps the 2015–2016 West Nile virus and Zika virus case counts across U.S. states, using a diverging color scale to encode total reported infections per state. The map renders as an SVG using D3 v3, with state boundaries and a color legend. It relies on two data files—West Nile virus counts (neuroinvasive and non-neuroinvasive cases, deaths, and blood donors) and Zika case counts—to color each state. The visualization is a fork of earlier D3 choropleth examples, and includes interactive tooltips that display the underlying state-level data on hover.
