This example demonstrates how D3.js can create horizontal bar charts using two different approaches within a single page. The visualization shows five data points displayed as teal bars in the first chart and red bars in the second chart, with bar widths proportional to the data values. The code uses D3’s selection and data binding methods—`selectAll`, `data`, and `append`—to generate the bar elements, while styling them with CSS classes. Notably, the first chart binds data to pre-existing divs without calling `enter()`, whereas the second chart uses `enter().append()` to create new divs dynamically. The source data is a hardcoded array of five numbers.

Barplot

This example shows two bar charts side by side, both visualizing the same array of numbers. The first chart renders the bars using a standard JavaScript for loop, while the second uses D3’s data join with `selectAll`, `data`, and `enter` to create the rectangles. Both charts are drawn as SVG elements, with static positioning for x and y coordinates and bar heights proportional to the data values. The code relies on D3 v5 APIs such as `d3.select`, `append`, and attribute setters, and includes background coloring, axis lines, and titles for each chart.

Entererer

Entererer is a minimal bar chart that visualizes a static array of five numeric values using D3.js v4. It shows a descending sequence of teal horizontal bars, each with a width proportional to its corresponding data point. The example demonstrates D3’s **enter selection** by using `d3.select('#chart')`, `.selectAll('div')`, and `.data(data)` followed by `.enter()` to create new `div` elements for each item, then sets their `class` to `bar` and computes the `width` style via a custom function. The rendering relies on standard HTML and CSS, with data hardcoded in the script.

Tutorial D3 2

This example demonstrates a horizontal bar chart that updates its bar widths based on a data array, using D3 v4 with SVG and animated transitions. It shows how to bind data to rectangles, handle enter/exit/update selections, and smoothly resize bars over one second. The code uses `d3.scaleLinear` for the width scale, `d3.scaleOrdinal` with `d3.schemeCategory20` for bar colors, and `transition().duration(1000)` to animate both entering and exiting bars. The visualization initially renders six bars with values from a hardcoded array, highlighting basic D3 data-join patterns.

d3js Exercice 4 - selection, data

This example demonstrates a basic data join with D3.js v4, where an array of five numeric values drives the widths of five horizontal bars. The visualization shows how selection and data binding work by pairing each number with a `<div>` element, applying a CSS class and dynamic pixel widths based on the data. The code uses `d3.select` and `selectAll` to target the container, then the `.data()` method to bind the array, followed by `.attr()` and `.style()` to update the bars. Commented exercises hint at extending the example with `.enter()` and `.exit()` for dynamic element creation and removal, though the visible implementation only performs the initial update. The static bars, with heights and margins set via CSS, render from the hardcoded dataset.

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 join() example

This example demonstrates how D3’s `join()` method synchronizes data with SVG rectangles, showing a bar chart of Nobel Prize winners by country. The code calls `updateBars()` three times—with ten, four, and two data items—to illustrate how the selection automatically handles entering, updating, and exiting elements. Using D3 v7’s `selection.join()`, it replaces the separate `enter()`, `update()`, and `exit()` workflows. Bars are styled via the `.bar` CSS class with a DarkSalmon fill, and the script logs each datum and index to the console.

Sample Bar Chart

This example displays a randomized dataset of 25 numeric values as a series of vertical bars, with each bar’s height proportional to its corresponding data point. The bars are rendered as inline-block HTML `div` elements styled with teal backgrounds and fixed widths. The sample uses D3 v7’s data join pattern—`d3.select().data().enter().append()`—to bind the data and generate the bars, while `Math.random()` produces the source values. The visualization demonstrates a basic bar chart without axes or scales, relying on a simple pixel-to-value mapping.

Learn D3 in 5 minutes

This example demonstrates the fundamental D3 data-join pattern by binding an array of five numbers to SVG rectangles, with each rectangle's width proportional to its corresponding value. The code selects an SVG container, calls `selectAll('rect')` followed by `.data(data)` and `.enter()`, then appends rects with width attributes set directly from the data. Using D3 v4 and vanilla JavaScript within an HTML page, it renders a simple vertical bar chart where bar heights are fixed by the `barHeight` variable and positioned via `translate` transforms. The visualization serves as a minimal introduction to D3's enter selection and chained attribute methods.
