Five plain rectangles sit in a row, each representing a hard-coded numeric value from an array. The example demonstrates how D3’s data join works with a static SVG selection, binding the array `[100, 250, 175, 200, 120]` to existing `rect` elements via `d3.selectAll('rect').data(data)`. No scales or axis are used, and no explicit update or exit handling appears, so the visualization only shows the initial selection and data binding step rather than any dynamic re-rendering. The SVG markup is minimal, with five empty rects defined directly in the HTML.

Three green rectangles of varying heights stand in a row on a blank SVG canvas, each bar’s x-position and height mapping directly to the same numeric value from a hardcoded three-element array. The visualization uses D3 v4’s data join (`selectAll`, `data`, `enter`) to append `rect` elements, setting their `width` to a fixed 25 pixels while deriving `height` and `x` from each datum. The SVG container is created via `d3.select("body").append("svg")`, with the chart’s simplistic styling and minimal layout emphasizing the direct translation of data values into geometric properties.

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.

This example shows a simple bar chart with five blue rectangles arranged horizontally, where each bar’s height corresponds to a value in a small hardcoded array. The chart uses SVG rectangles bound to the data via d3.v4’s selection.data, with x positions computed from an index and y positions derived from a fixed chart height minus each bar’s value. The code sets width, height, fill, and stroke attributes directly on the rect elements, producing a basic static visualization without axes or labels.

This example shows five blue rectangles positioned side by side in an SVG, with heights corresponding to an array of numbers (100, 250, 175, 60, 150). The rectangles are drawn on a baseline at the bottom of the viewport, creating a simple bar chart. The code uses D3 v4’s `selection.data()` and `selection.attr()` methods to bind the data and set each rectangle’s x, y, width, height, fill, and stroke attributes. The `height` variable is referenced but not explicitly defined, so the vertical placement relies on the SVG’s default coordinate system.

This example visualizes a small set of six rectangles, each positioned and sized by explicit x/y coordinates and width/height values, with colors assigned individually. It shows the spatial arrangement of these shapes on an SVG canvas, computed by finding the maximum extents of all rectangles to set the canvas size. The code uses D3 v3 to bind the JSON data to `rect` elements, setting position and size attributes, while also appending a canvas element to the body. The data source is inline in the script, and the rendering relies on standard SVG attributes.

Four orange circles are drawn on a blank SVG canvas, each sized and positioned proportionally to its corresponding value in the static array `[10, 30, 50, 100]`. The example demonstrates a basic data join using d3.v5, where `selectAll("circle")` and `.data()` bind the array elements, and `.enter()` appends the shapes. Circle radii and y-coordinates reflect the data values directly, while x-coordinates increase with index. The visualization shows a simple, non-interactive mapping of numbers to visual attributes, with no axes or labels included.

This example shows a simple bar chart of five value sizes (155, 250, 175, 200, 120) rendered as blue rectangles with white strokes on an SVG canvas. The bars are positioned horizontally by index and vertically from the bottom, with heights proportional to each data value. The visualization uses the D3.js v4 library’s `select`, `selectAll`, and `enter().append()` API to bind the data array to `rect` elements, computing x, y, width, and height attributes directly from the data and a constant `rectWidth` of 50 pixels.

This example shows a static SVG scene with a red square and an orange circle, followed by a D3 script that generates additional blue and green rectangles whose positions and heights derive from an array of five numbers. The code uses the D3 library (version 3.5.5) to select the SVG, append a rectangle, and bind the data array to a `selectAll("rect")` operation, setting each rectangle's `x`, `y`, and `height` attributes through anonymous functions. The rendering is purely SVG-based, with no interaction or animation.
