This bar chart displays average house prices for regional and national areas, using two purple-and-pink bars on a light background. It loads JSON data via `d3.json`, encodes the x-axis with `d3.scaleBand` and the y-axis with `d3.scaleLinear`, and formats y-axis ticks as thousands with "K". A custom tooltip div appears on `mousemove`, showing the area name and price, and disappears on `mouseout`. The chart uses conventional margins, `d3.axisBottom` and `d3.axisLeft`, and renders in SVG.

ice5.1

This bar chart compares house prices across different house sizes, with teal bars representing each category and rotated labels on the x-axis for readability. The visualization uses D3 v7 to load CSV data from a GitHub gist, scales the data with `d3.scaleBand` and `d3.scaleLinear`, and renders the chart as SVG. Axes are generated using `d3.axisBottom` and `d3.axisLeft`, while the plot area measures 900 by 380 pixels with margins. The code directly binds the data to rectangle elements for each bar.

FP: Bar Chart

This bar chart visualizes house sale prices across different regions, with each bar colored by region using an ordinal color scale. The interactive color legend allows users to hover over a region to highlight matching bars and fade the rest, implemented with D3.js enter/update/exit selections and hover state management. The chart is built from house sales data (houseRocket.csv) and uses a clean, minimal design with bars representing price values. Hovering over the legend highlights corresponding bars in the chart while dimming others, and hovering over bars emphasizes their legend entry. The visualization uses a sans-serif font, square color swatches, and a pointer cursor for interactive elements, with smooth opacity transitions for the hover effects.

Making a Bar Chart Fork

This example visualizes the average price of a two-bedroom flat across ten countries, using a horizontal bar chart rendered as SVG. The chart orders countries by price and labels each bar with its value in thousands. The code uses D3 v5 utilities including `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom`, with data loaded from a CSV file via `d3.csv`. A `format('.3s')` tick formatter abbreviates axis labels, while the bars themselves are styled with a steelblue fill.
