This example displays a choropleth map of the United States, with each state filled with a distinct color from a categorical scale and a hover effect that turns the state white. It uses D3 v7’s `geoAlbersUsa` projection and `geoPath` to render the map from TopoJSON data loaded from the us-atlas CDN. State boundaries are drawn with black strokes, and tooltips showing state names appear via appended `title` elements. The color mapping and hover behavior are implemented with `scaleOrdinal` and CSS `:hover` rules.

ICE8-1.2

This example renders a choropleth-style map of U.S. states using a categorical color scale based on state names. It uses D3 v5’s `d3.geoAlbersUsa` projection and `d3.geoPath` to draw state boundaries from TopoJSON data loaded from the us-atlas CDN, with state labels positioned at each polygon’s centroid. The code also applies a sequential color palette via `d3.scaleOrdinal` and `d3.schemeCategory10`, and includes hover tooltips via appended `title` elements. The map is rendered as SVG, with black stroke outlines for each state.

Data Visualization ICE8 - Country Map

This example displays a choropleth-style map of the United States using red-filled states with blue outlines and green hover states. Built with D3 v5 and TopoJSON, it loads US Atlas state boundaries and projects them using `geoAlbersUsa`. The `geoPath` generator renders each state as an SVG `<path>`, with a `<title>` element revealing the state name on hover. The map uses the `geo-albers-usa-territories` library for accurate territory placement.

Country Map- ICE 8

This example displays a choropleth-style map of the United States, coloring each state with a uniform dark teal fill and a light stroke. Hovering over a state changes its fill to a pale cream, providing a simple interactive highlight. The visualization uses D3 v5’s `geoPath` and `geoAlbersUsa` projection, combined with TopoJSON’s `feature` method to parse state boundaries from a remote JSON file. The SVG rendering is styled via a linked CSS stylesheet, with hover effects applied through the `.states:hover` class.

ICE8 USA Map

This example shows a choropleth-style map of the United States, with each state rendered as a red path that turns blue on hover and includes a tooltip with the state name. The map is drawn using D3’s `geoAlbersUsa` projection and `geoPath` generator, fed by TopoJSON state boundaries from the `us-atlas` dataset. The code uses `d3.json` to load the data, `topojson.feature` to extract geometries, and appends SVG paths with CSS-based hover styling.

usa map

This example displays a choropleth-style map of US states, with each state filled by a categorical color from `d3.scaleOrdinal` and `schemeCategory10`. It uses `d3.geoPath` with a `geoAlbersUsa` projection to render the SVG paths, and the state boundaries are loaded from a TopoJSON file via `us-atlas`. Hovering a state changes its fill to yellow, while a red stroke outlines all boundaries. The code processes the TopoJSON with `topojson.feature` and appends a `<title>` element for each state name.

ICE8 USA Map

This example displays a choropleth-style map of the United States, with each state filled in green and outlined in a semi-transparent orange. It shows the geographic boundaries of all 50 states, highlighting them in red on hover. The visualization uses the D3 v5 library with `d3.geoPath` and `geoAlbersUsa` projection, rendering the map as SVG paths from TopoJSON data loaded from the us-atlas repository. The `states-10m.json` file provides the geographic features, and the `geo-albers-usa-territories` plugin enables territory inclusion.

ICE8 USA Map

A choropleth-style map of the United States renders each state as an SVG path, colored with a categorical scale and labeled with its name at the centroid. Hovering turns a state red via CSS. The code loads TopoJSON state boundaries from the us-atlas package and uses `d3.geoAlbersUsa` for projection, `d3.geoPath` to generate paths, and `d3.scaleOrdinal` with `schemeCategory10` for fill colors.

ICE8 USA Map

This visualization displays a choropleth map of the United States, with state boundaries drawn as SVG paths. The code uses D3 v5’s `geoAlbersUsa` projection and `geoPath` to render geographic features from TopoJSON data loaded from the us-atlas repository. Each state shape is colored with a default fill, and hovering changes the fill color via CSS. State names appear as tooltips using SVG `title` elements, sourced from the TopoJSON feature properties.
