A choropleth map of the United States visualizing 2016 Zika virus case counts by state, with states drawn as SVG paths and colored according to the number of reported cases. The map is rendered using D3 v3, with each state path defined in the included uStates.js file. Hovering over a state triggers a tooltip displaying the state name and its case count, with the state's fill opacity changing on hover. The visualization is static with no animation, though the code includes a reference to a CSV data file that appears to be incompletely integrated into the data-binding logic.

A choropleth map of the United States visualizing Zika virus case counts by state in 2016. States are drawn as SVG paths and colored using an interpolated gradient from pink to green based on case data loaded from a CSV file. Hovering over a state triggers a tooltip that displays the state name along with low, average, and high case estimates. The map is rendered with animated transitions as the data loads, and states highlight on hover with reduced opacity.

This animated choropleth map visualizes reported Zika cases across U.S. states in 2016, drawing state boundaries from the included uStates.js dataset and loading case counts from a CSV file. Each state is colored using an interpolated scale from pink to green based on randomized low, average, and high case values, with a hover tooltip displaying these figures. Built with D3 v3 and SVG, the map renders state paths and animates the tooltip on mouseover, providing an interactive overview of the data.

This visualization shows a choropleth map of the United States colored by reported Zika virus cases from a 2016 dataset. Each state is filled with a sequential orange color scale using a log transform, so the fill reflects the relative case counts. Hovering over a state triggers a dark tooltip that displays the state name and its case total, while the state itself becomes slightly transparent. The map is rendered in SVG and animated states update as the data loads, with the color scale computed dynamically from the data range.

This choropleth map of the United States visualizes Zika virus case counts by state, colored with a pink-to-green interpolated scale. As the page loads, a CSV of 2016 Zika cases is loaded and joined to the state geometries. Each state is rendered as an SVG path and colored according to its case count, with hover interactions that trigger a dark tooltip displaying the state name, low, average, and high case values. The map also includes Alaska and Hawaii insets, and the animation effect is provided by the hover opacity change.

This interactive choropleth map visualizes reported Zika virus cases across U.S. states using a custom GeoJSON path dataset. States are outlined in gray and become semi-transparent on hover. A tooltip appears on mouseover, displaying the state name and case count, though the data-loading logic is incomplete and sampleData remains empty. The map is rendered as an SVG with D3 v3, with static state boundaries and no animation.

US State Map

A choropleth map of the United States displays Zika virus case counts by state, with darker purple shades representing higher case numbers. Hovering over a state reveals a tooltip with the state name and its total case count. The visualization uses d3.csv to load the zika_2016.csv data, and the uStates.js library to draw the SVG state paths. Interactive hover effects and tooltips are implemented with D3 event handling and a custom HTML tooltip, providing a clear geographic overview of the outbreak's distribution.

US State Map

This visualization displays a choropleth map of the United States showing reported Zika virus cases by state in 2016. Each state is colored on a gradient from black to white based on its case count, with hover interactions that reveal exact figures through a tooltip. The map is rendered as SVG using D3 v3, with state paths and data loaded from CSV files via `d3.csv`. The tooltip displays case data alongside a simple table, and the `uStates.draw` function handles map rendering and interactions.

US State Map

This example presents a choropleth map of the United States, with each state colored according to the number of Zika virus cases reported in 2016. The visualization uses D3.js v3 to render the map as SVG paths and includes a hover tooltip that displays the total case count for each state. The map is drawn using the `uStates.js` library, which defines the state path geometries, while `d3.csv` loads the data from a local file. State colors are determined by a single interpolated value, and the code includes a mouseover effect that reduces fill opacity.
