This example visualizes the average energy price by country, computed from a CSV file of daily energy records. The code aggregates energy prices per country, calculates each country’s mean, and renders a bar chart using SVG. It employs D3 v7’s `scaleBand` for the x-axis and `scaleLinear` for the y-axis, along with `d3.csv` to load the data and `d3.axisBottom` and `d3.axisLeft` for the axes.

Average Energy Price by Country

A bar chart displays the average energy price for each country, with each bar representing a country’s mean value calculated from the dataset. The visualization uses D3 v7 to load the CSV file, aggregate energy prices by country, and render SVG rectangles. A linear scale maps average prices to bar heights, with axes labeled and rotated country names for readability.

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.

Fork of HTML Starter

This visualization shows global renewable energy production statistics by country and year, displaying average and maximum production values alongside a bar chart. The chart encodes each country-year combination on the x-axis with production in terawatt-hours on the y-axis, using hover effects to highlight individual bars. The implementation loads CSV data from a GitHub gist via `d3.csv`, computes summary statistics with `d3.mean` and `d3.max`, and renders an SVG bar chart using `d3.scaleBand` and `d3.scaleLinear` with `d3.axisBottom` and `d3.axisLeft`. The page is styled with CSS and built with D3.js v7.

DV ICE-6 Bar Graph

This chart displays the average gas prices per gallon for fifteen countries, using horizontal bars sorted by country name. The visualization loads data from a CSV file via `d3.csv`, then maps the price values to bar widths using `d3.scaleLinear` and country names to y-axis positions with `d3.scaleBand`. The React component renders an SVG, with gridlines generated from `xScale.ticks()`, and sticks to a functional, no-frills style without color or labels on the bars themselves.

Fork of D3 Starter

This example displays a bar chart of average energy consumption by household appliance, sourced from a CSV file. It uses D3 v7 to load the data, construct linear and band scales, and render SVG rectangles for the bars, with rotated axes labels. The visualization adds a descriptive title and applies a blue fill to each bar via the `d3.scaleBand` and `d3.scaleLinear` APIs.

Fork of Fork of Fork of ICE-6 Bar Graph

This horizontal bar chart visualizes the average monthly cost of basic internet service across twelve countries, sourced from a CSV file loaded via D3’s `csv` function. It shows the data before explaining the mechanics: each bar’s length encodes cost, with country names on the y-axis using a `scaleBand` and costs on the x-axis via `scaleLinear`. React manages the component state and rendering, while D3 handles the scales, axes, and bar positioning. The visualization uses SVG elements, with gridlines drawn from `xScale.ticks()`, and fetches data asynchronously inside a `useEffect` hook, displaying a loading state until the data arrives.

Fork of Fork of Fork of ICE-6 Bar Graph

This example shows the monthly cost of basic Amazon services across different countries, displayed as a horizontal bar chart. The visualization ranks twelve country codes by their associated costs, with a red gridline marking each value on the x-axis. The chart uses pre-loaded CSV data and renders in SVG via React. It implements D3 version 5’s `scaleBand` and `scaleLinear` to map country codes and cost values, while `csv` fetches the external dataset and `max` calculates the domain for the value axis.

Fork of Fork of Fork of ICE-6 Bar Graph

This visualization displays a horizontal bar chart of the first 12 countries from an external CSV, ranking their basic monthly internet costs in US dollars. The chart encodes cost values as bar lengths on a linear scale, with a red axis grid for reference. Built with React and D3 v5, the code uses `csv` for data loading, `scaleBand` and `scaleLinear` for coordinate mapping, and renders the chart as SVG elements within a React component.
