This example demonstrates a simple bar chart that visualizes municipal census data from a JSON file, showing municipality names alongside their census values. The visualization uses D3 v5’s data join pattern to bind dataset elements to SVG rectangles and text labels, sorting bars in descending order and scaling bar widths with `d3.scaleLinear`. The code loads data asynchronously via `d3.json` and renders two separate SVG containers, though only the first is populated. Text labels are positioned manually without an x-coordinate, leaving them at the SVG’s default origin.

D3 DataBinding

This example demonstrates a simple bar chart that binds JSON data to SVG elements, showing municipal census values as horizontally sorted bars. The visualization uses D3.js v5 to load data from a GitHub-hosted JSON file and renders two separate SVG containers, though only the first is populated. The code employs D3’s data join pattern with `selectAll`, `data`, and `enter` to append rectangles for bars and text labels for municipality names. A linear scale maps the data domain to pixel widths, while bar heights are fixed and y-positions are computed by index. The chart sorts data in descending order by census value before rendering.

D3 DataBinding

This example shows a simple bar chart built with D3 v5, displaying census data for municipalities from a JSON dataset. The visualization renders two SVG elements, though only the first is populated with data. The code uses `d3.scaleLinear` to map census values to bar widths and `d3.ascending`/`d3.descending` for sorting. It demonstrates data binding with `selectAll` and `enter().append()` to create rectangles and text labels, though the label positioning is incomplete. The data is loaded via `d3.json` from a GitHub-hosted source.

D3 DataBinding

A simple bar chart visualizes municipal census data using two SVG elements, where each bar's width maps to a numeric census value via `d3.scaleLinear`. The code loads JSON data from a GitHub repository using `d3.json` and binds it to rectangles and text labels with `.data()` and `.enter()`. Bars are sorted in descending order and labeled with municipality names, while the chart dimensions derive from the SVG attributes. Built with D3 v5, the example demonstrates basic data joins for both shapes and annotations, though it only renders one of the two defined chart instances.

D3 DataBinding

Two small bar charts display municipal census data as horizontal steelblue bars, sorted in descending order by population. Each bar is labeled with its municipality name in small sans-serif text. Built with D3 v5, the example uses `d3.json()` to load data and `d3.scaleLinear()` for the x-axis scale, with `selectAll().data()` and `enter()` appending SVG `<rect>` and `<text>` elements. The data comes from a GitHub-hosted JSON file.

D3 DataBinding

This example demonstrates a basic scatterplot-style bar chart created with D3 v5, showing census data for Colombian municipalities loaded from a JSON file hosted on GitHub. The chart uses a linear scale (`d3.scaleLinear`) to map census values to horizontal bar widths, with rectangles appended to an SVG element via D3’s data join (`selectAll`, `.data`, `.enter`). Bars are sorted in descending order using `d3.descending` and rendered with a fixed height, while the dataset is fetched asynchronously with `d3.json`. The visualization emphasizes D3’s core data-binding pattern for simple, static SVG rendering.

D3 bar chart with data-binding

This example demonstrates a simple D3 bar chart that binds an array of numeric values to SVG rectangles, with each bar’s height proportional to its data point. It uses D3 v4’s `scaleLinear` to map the data domain to a fixed pixel range, then applies the `data()` and `enter()` methods to create and position the rectangles. The chart renders with a minimal style—unfilled bars with black outlines—and the data is hardcoded as a static array. The code relies on standard D3 selection and scale APIs, with the SVG container set to 960 by 500 pixels.

D3 in depth

This example shows horizontal bar charts for the populations of five cities, with city names positioned to the right of each bar. A hover effect changes the bar color from steelblue to orange. The visualization is built with D3 v7, using selections, data binding, and the `join` method to create SVG `rect` and `text` elements. The data is hard-coded in an array of city objects, and bar widths are scaled by multiplying population values by a constant factor.

data join

This example demonstrates the D3 data join pattern by binding an array of city population objects to SVG rectangles and text labels, producing a simple horizontal bar chart. The code uses `select` and `data` from D3 v7, with the `.join` method to create elements for each datapoint. Rectangles are sized proportionally to population via a scale factor, while a separate join on a `.labels` group renders each city’s name. The SVG canvas is fixed at 2000×2000, with five cities hardcoded in the script.
