This visualization combines a U.S. state boundary map with red, green, and blue proportional circles to depict cost-of-living indices across states. Circle sizes scale linearly with each state's cost index using `d3.scaleLinear`, while positions are projected with `d3.geoAlbersUsa` and `d3.geoPath`. Data from `expstates.csv` is rendered in an SVG, and the ten highest-cost states are highlighted in green via a tooltip showing state names and indices.

A9 - Proportional Symbols Map in D3

This D3.js proportional symbols map visualizes the cost of living index across US states. Gray states are drawn with the `d3.geoAlbersUsa` projection and `d3.geoPath`, while semi-transparent red circles, sized by a square-root scale, are placed at state coordinates derived from an external latitude/longitude source. A legend displays four bubble sizes with corresponding index values. Hovering over a circle reveals a tooltip with the state name and cost index. Data is loaded via `d3.json` and `d3.csv`.

Proportional Symbols Map

This visualization shows a proportional symbols map of U.S. states, where circle size encodes each state’s cost index and the top nine highest-cost states appear in red. It uses D3 v7 with SVG rendering, a `d3.geoAlbersUsa` projection, and `d3.geoPath` for both state boundaries and symbol placement. A `d3.scaleSqrt` maps cost indices to circle radii. The code loads state polygons from us-states.json and point data from expensive-states.json, adding tooltips on mouse events.

A9: D3 Proportional Symbol Map

This proportional symbol map shows the relative cost of living across US states using colored circles sized by each state’s cost index, with tooltips on hover. The visualization loads US state boundaries from a TopoJSON file via `d3.json` and `topojson.feature`, then plots the CSV data points using `d3.geoAlbersUsa` and `d3.geoPath`. Circle radius and fill color are scaled with `d3.scaleSqrt` and `d3.scaleLinear`, respectively. It uses D3 v7 with SVG rendering, a color legend, and animated opacity and stroke transitions for interactive highlighting.

A9-Proportional Symbols Map

This proportional symbols map visualizes the relative cost of living across US states, using the area of each circle to represent its cost index. Hot pink circles mark the top ten most expensive states, while purple circles denote all others. Built with D3 v7 and TopoJSON, it projects state boundaries using an Albers projection via `d3.geoPath` and scales circle radii with `d3.scaleSqrt`. Interactive tooltips appear on hover, displaying each state's name, cost index, and rank. The map overlays state outlines with data from a CSV of state cost indices.

Proportional Symbols Map

A Proportional Symbols Map displays the cost index for each U.S. state, with larger circles indicating higher costs and the top ten states highlighted in red. The visualization uses a Mercator projection via `d3.geoMercator` and `d3.geoPath` to render state boundaries from a GeoJSON file. Circle radii are scaled from CSV data, and `d3.scaleThreshold` with `d3.schemeBlues` provides color encoding. The map is drawn in SVG with D3 v6, using `join()` to bind data points to circle elements and tooltips showing state names and cost values.

A9 Proportional Symbols Map D3

This map visualizes the costliness of states across the US, with each state’s centroid marked by a proportional circle whose size reflects its expense rank. The Albers USA projection renders the geographic backdrop, while the circles are colored to highlight distinctions. Built with D3 v7 and the TopoJSON library, it uses `d3.geoAlbersUsa()` and `d3.geoPath()` to draw the map. An interactive tooltip appears on hover, displaying details about each state.

A9 Proportional Symbols Map

This proportional symbols map displays transportation costs for U.S. states, with circle size scaled by each state’s cost index and red circles highlighting the top ten most expensive states. It renders via D3.js v7 using `d3.geoAlbersUsa`, `d3.geoPath`, and `topojson-client` to draw state boundaries, while `d3.scaleSqrt` maps cost values to circle radii. Hovering reveals a tooltip with the state name and cost. The legend indicates cost ranges, and the underlying CSV data provides geographic coordinates.

[A9] Cost Index per State (Proportional Symbols)

This proportional-symbol map visualizes the cost index for each U.S. state, with circle size encoding the index value and the top 10 states highlighted in black. The visualization uses D3.js v7 with a Mercator projection via `d3.geoPath()` and `d3.geoMercator()`, rendering state boundaries as SVG paths. State coordinates and cost index data are loaded from CSV files, while geographic boundaries come from a GeoJSON source. Circles positioned at state centroids use radius values scaled from the cost index, with tooltips showing exact values.
