Five rectangles render as a simple bar chart in an SVG canvas, with bar heights mapping to values in a hardcoded JavaScript array. The code uses D3 v4’s data join pattern: `svg.selectAll('rect')` binds the array, then `.enter().append('rect')` creates the bars, positioning each with `x` and `y` attributes calculated from index and data value, and styling them blue with white strokes.

SVG Example

Five static SVG rectangles form a simple bar chart, descending diagonally from the top-left to the bottom-right. The bars have equal widths and varying heights and y-positions, creating a staircase-like visual from a hardcoded JavaScript array of objects. The example uses D3 v4’s selection API to append rectangles to an SVG canvas, setting x, y, width, and height attributes from the data. The code demonstrates basic declarative binding of data to SVG shapes without animation or axes.

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.

This example shows a simple bar chart built with D3 v4, where four blue rectangles represent values from a small array. The bars scale vertically from a fixed height, with their y-positions calculated as the height minus each data value. Using `d3.select` and `d3.selectAll`, the code binds the data array to SVG `rect` elements via `data()`, then appends them with `enter()`. Each bar’s width is set to a constant 100 pixels, and positions are assigned with `attr('x')` based on index times that width. The SVG output uses `fill` for blue bars and `stroke` for white outlines.

Enter append etc

Two interactive rectangles act as buttons for updating a data-driven circle chart in D3.js. The example demonstrates the enter and append pattern, where clicking `rect1` replaces the dataset with a new array of three values, and clicking `rect2` adds two additional circles. Initially, three circles are rendered with radii proportional to the square root of the data values. The code uses `d3.selectAll("circle").data()` and `.enter().append()` to create new SVG circle elements, with transitions animating the radius updates.

HTML Starter

A simple bar chart renders three static rectangles from a hard-coded array of three values. The example demonstrates basic D3 data binding with `d3.select`, `canvas.selectAll`, and `.enter()`, appending SVG `rect` elements whose width and height are derived from each data point. The chart uses D3 v5 and outputs to an SVG canvas, with bars positioned vertically by index. No axes, scales, or interactivity are included, making it a minimal starter template for understanding core D3 joins.

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.

SVG Example

This example displays a simple bar chart with five bars labeled A through E, where bar heights correspond to values from 5 down to 1. The visualization uses D3 v4’s `d3-selection` to bind data to SVG `rect` elements, and `d3-scale` with `scaleBand` for the x-axis positions and `scaleLinear` for the y-axis scaling. The page creates an SVG canvas in the body and renders all bars via chained `enter()` and `append` calls, with no axes or labels added.

A set of five blue rectangles forms a simple bar chart, with each bar’s height directly proportional to values from an inline array. The code uses D3 v4’s selection and data-binding methods (`selectAll`, `data`, `attr`) to map each data point to an SVG `rect`, positioning bars side‑by‑side along the x‑axis and scaling their y‑positions and heights from a fixed baseline. The bars are evenly spaced using a constant `rectWidth`, while the SVG’s total height is fixed at 300 pixels. The chart is rendered entirely with SVG elements and hardcoded data, without scales or axes.
