Forked from Margins

This example demonstrates the fundamental concept of margins in data visualization by drawing a gray rectangle that sits inside a larger white canvas, with padding on all four sides. The code uses D3.js (version 7.8.5) and its `select` API to create an SVG element, then renders the rectangle with computed dimensions based on the container’s client width and height minus fixed top, left, bottom, and right margins. The inner rectangle’s size is calculated from those margin values, and a fill color of `#808080` distinguishes it from the surrounding space.

Viz Function concept

This example demonstrates how D3 margins define the inner plotting area within an SVG canvas. It renders a single gray rectangle positioned at the top-left margin boundary, with its width and height calculated by subtracting the margin values from the total container dimensions. The visualization uses D3’s selection join operator to create and update the SVG and rectangle elements, leveraging the `select`, `selectAll`, and `join` APIs. The container’s client width and height determine the overall canvas size.

Viz Function Concept

This example demonstrates the Viz Function concept, a refactoring that encapsulates configurable logic for graphics and visualization. The main script imports a `viz` function from `./viz` and calls it with parameters for dimensions and an inner rectangle fill color, rendering an SVG with a gray inner rectangle inside the container. The `viz` function uses D3’s `select` and `join` APIs to create and update the SVG rectangle, calculating its size based on provided margins. The code relies on the D3 library (version 7.8.5) and is structured as a reusable, parameterized visualization component.

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.

Fork of Viz Function Conceptdrb

This example demonstrates a reusable "viz function" pattern for structuring D3.js graphics. It renders a simple rectangle with configurable margins, dimensions, and fill color, computed from the container size. The code separates the visualization logic in `viz.js`, which accepts an SVG selection and an options object, while `index.js` initializes the SVG using D3's `select` and `join` methods. This refactoring highlights how to encapsulate and parameterize chart code for flexibility.

Margins

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.

react-d3

This React and D3 example demonstrates a reusable SVG container component that establishes a standard margin convention for data visualizations. The `VizContainer` component abstracts the SVG and group elements, rendering a gray background rect and an inner plotting area with a transform translation. Using React and ReactDOM for the component structure, it accepts width, height, margin, and inner dimensions as props, with an optional `showMargins` flag to display the boundary rectangles. The code sets up a 960x500 canvas with 30-pixel margins, providing boilerplate for future chart development within the translated coordinate system.

RightAxis

This example displays an empty SVG canvas with visible margins, demonstrating a reusable React and D3 container component called `VizContainer` that abstracts SVG grouping and follows the margin convention. The component renders an outer and inner rectangle to highlight the plotting area, with conditional `showMargins` prop controlling their display. It uses `React.createElement` and JSX, with dimensions and margins defined as variables, and leverages the `d3` library version 6 for future charting. The setup includes CDN links for React, ReactDOM, and d3, providing a boilerplate foundation for adding custom visualizations.

Hello VizHub

This example demonstrates how to create a simple SVG visualization using D3.js within the VizHub environment. The code imports the `select` function from the D3 library and applies it to the page’s `svg` element, setting its background color to red. The accompanying HTML loads D3 v5.9.1 from a CDN and defines an empty 560×960 SVG canvas, while the CSS styles the page background, text, and font using the Ubuntu typeface from Google Fonts. The result is a minimal, static visual with no data processing or interactive elements.
