This visualization demonstrates the concept of inner margins in a chart, showing a gray rectangle that represents the area reserved for data marks, surrounded by empty space for axes. The code uses D3’s `select` and `join` methods to create an SVG element sized to the container, then draws the inner rectangle with fixed 50-pixel margins on all sides. The example highlights how explicit margin calculations (using `innerWidth` and `innerHeight`) define the plotting region, using D3 version 7.8.5 to render the static shape.

This example demonstrates how to define the boundaries of a visualization using margins, rendering a fixed gray inner rectangle on an SVG canvas. The outer container dimensions are read directly from the page, then margin values create a centered plotting area of a specified size. The code uses D3.js’s `select` and `join` methods to append the SVG and its rectangle, calculating the `innerWidth` and `innerHeight` by subtracting the margins from the container size. This setup ensures space is reserved for future axes or chart elements.

This example demonstrates how margins frame a visualization’s drawing area. A single gray rectangle sits inside an SVG canvas, inset by a uniform 22-pixel margin on all sides. The code uses D3’s `select` to create the SVG and computes the inner dimensions by subtracting the margin from the container’s size. The rectangle is rendered with `attr` for positioning and fill, showing the reserved space around the plot region.

This example demonstrates SVG margins by rendering a single gray rectangle positioned inside a computed inner area. The visualization uses D3 v7, specifically the `select` function, to create an SVG canvas sized to the container and draw a rectangle with explicit margin offsets. The code calculates inner dimensions by subtracting margin values from the full width and height, then places the rectangle at those margin coordinates. The gray fill highlights the inner plotting region, making the margin concept visually explicit through the resulting bordered layout.

This example demonstrates how margins define the inner rectangle of a visualization, using a red rectangle to clearly show the area where data marks are drawn. The code sets fixed margin values for the top, bottom, left, and right, then calculates the inner dimensions by subtracting them from the container's width and height. It uses D3's `select` API with a `join` operation to create and size the SVG and its child rectangle, illustrating the fundamental layout step before adding axes or data.

This example demonstrates how margins define the inner rectangle of a visualization, reserving space for axes while constraining the area for marks. It uses D3.js version 7.9.0, specifically the `select` API, to render an SVG that fills the container. The code calculates the inner width and height by subtracting fixed 50-pixel margins from the container dimensions, then draws a gray rectangle (`#B5B5B5`) positioned at those margin offsets. The rendered output is a static filled rectangle, serving as a template for layout structure.

This example demonstrates how margins define the inner rectangle of a visualization, reserving space for axes and marks. The chart renders a neon green rectangular plotting area with a single green circle at coordinates (308, 390), positioned relative to the container’s client dimensions. Using D3.js (version 7.8.5), the code leverages selections and joins to create the SVG elements, computing inner width and height by subtracting fixed 50-pixel margins from the container size. A gray gradient background is applied via CSS, and the data itself is hardcoded as placeholder values.

This example demonstrates the fundamental visualization layout pattern of defining margins to create an inner rectangle for chart content. A gray rectangle is drawn within the container, positioned according to specified top, right, bottom, and left margins, with its dimensions calculated by subtracting those margins from the container’s total width and height. The code uses a ResizeObserver to track container size changes and updates the state accordingly, then renders the rectangle with D3’s `select` and `join` methods. The visualization adapts responsively as the container resizes, showing how margins reserve space for axes and other chart elements.

marginConvention

This example demonstrates a basic SVG chart layout using the margin convention in D3. It shows how to structure a visualization by setting explicit margins, calculating the inner width and height, and translating a group element to establish the plotting area. The code uses d3.select and append to create an SVG, then draws a light blue rectangle with a green stroke to represent the chart region. The chart background is light gray, with the margin values set to top 0, right 0, bottom 20, and left 25. The full SVG dimensions are 425 by 625 pixels, rendered with D3 v4.
