This example demonstrates a grouped bar chart of the top 10 countries by population, using a D3 join pattern. It shows how to append a group element per data point containing both a bar and a text label, with the enter selection handled via `.join()` and `.call()`. The visualization uses `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.axisLeft` from the axes library. Data comes from the UN population estimates 2024, sorted in descending order.

A response to the question:

Do you have a good example of a D3 grouped selection? I can never remember how to do the pattern and don't do it often enough. For example an SVG group (for each data element) that has say a bar and a label within it. Appending is easy, joining is where it gets a bit more gnarly

D3 Grouped Selections

This example demonstrates a grouped selection pattern in D3, where the top 10 countries by population from the UN population estimates dataset are rendered as SVG groups, each containing a bar and a text label. The visualization shows a bar chart with country names on the x-axis and population values on the y-axis, using `d3.scaleBand` and `d3.scaleLinear`. The core technique uses `.selectAll('g.mark').join()` with an enter function that appends both a `rect` and `text` element per group, then updates their attributes via nested `.select()` calls. The code imports from `d3` and uses the `@curran/responsive-axes` library for axis handling.

Fork of Making a Bar Chart

This example displays a horizontal bar chart of the top 10 most populous countries, based on 2018 United Nations data. It uses d3.scaleLinear and d3.scaleBand to map population values and country names, with d3.axisLeft and d3.axisBottom for the axes. The chart customizes the x-axis tick format to show values in billions and removes axis domain and tick lines, while the title and axis label are added as SVG text elements.

Fork of Fork of Making a Bar Chart

This bar chart displays the population of the top 10 most populous countries based on 2018 estimates from the United Nations World Population Prospects. It shows how D3 v5 axes can be customized to improve readability of the value labels. The SVG rendering uses d3.csv to load data and d3.scaleBand with d3.scaleLinear for positioning, while d3.axisBottom creates the x-axis. The page also includes a separate SVG element demonstrating a circle update pattern with d3.select and .join.

Fork of Making a Bar Chart

This bar chart displays the top 10 most populous countries using 2018 population estimates from the United Nations World Population Prospects. Built with D3 v5, it uses `scaleLinear` and `scaleBand` for positioning, with `axisBottom` and `axisLeft` for labels. Population values are formatted with `format('.3s')` and converted from thousands. The chart renders as SVG, includes gridlines via tick sizes, and omits unnecessary axis domains and tick lines for a cleaner presentation.

Fork of Making a Bar Chart

This bar chart displays the top 10 most populous countries based on 2018 United Nations estimates, with population values scaled in thousands. Using D3 v5, the visualization employs `scaleLinear` and `scaleBand` to map population counts and country names, while `axisBottom` and `axisLeft` render formatted axes with a custom tick format that converts large numbers to abbreviated units. The SVG rendering includes gridlines, a title, and an axis label, with horizontal bars styled in steel blue.

Fork of Making a Bar Chart

This example shows a horizontal bar chart of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The chart uses D3 v5 with an SVG rendering, scaling population values via `d3.scaleLinear` and country names via `d3.scaleBand`. It customizes the axes with `d3.axisLeft` and `d3.axisBottom`, applies a `.3s` tick format that replaces “G” with “B”, and removes default axis domain lines. The data is loaded from a CSV file using `d3.csv`.

Fork of Making a bar chart in D3.js

This example shows the population of the top 10 most populous countries, based on 2018 estimates from the UN World Population Prospects. A light blue SVG canvas renders horizontal bars, with country names on the left axis and population values on the bottom axis. The code uses d3.csv to load the data, d3.scaleLinear for the x-axis, d3.scaleBand for the y-axis, and d3.axisLeft and d3.axisBottom for tick labels. Bars are appended as SVG rect elements with steelblue fill via d3 selection and data joins.

This bar chart displays the population of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The visualization uses D3 v5’s `scaleLinear` and `scaleBand` to map population values and country names, with axes customized via `axisBottom` and `axisLeft`. Population values are formatted with `format('.3s')` to abbreviate large numbers, and the data is loaded asynchronously from a CSV file using `d3.csv`. The SVG rendering includes a title and axis label for clarity.
