This example demonstrates how to create a basic SVG element in D3 v4 by assigning its width and height to JavaScript variables. It shows the initial setup of an SVG container, setting its dimensions to 500 pixels wide and 50 pixels high, and appending it to the page body. The visualization uses d3.select and .append to construct the SVG, with no additional data binding or drawing operations shown. The resulting blank SVG serves as a foundation for future graphical elements.

17. D3 Drawing SVGs

This example demonstrates how to create an empty SVG container using D3.js version 4.5.0. The code selects the body element and appends an SVG with fixed width and height attributes, establishing the canvas for future visualizations. It uses d3.select and the append method to build the SVG structure, with no style rules or additional elements yet present.

d3 intro

This example demonstrates basic SVG shapes—a blue circle and a magenta rectangle—rendered on an HTML page, with a yellow SVG canvas sized at 900 by 500 pixels. The page also includes commented-out D3 code that would select the SVG, set its dimensions, apply a light blue background, and append a circle at new coordinates. The visible output relies on static SVG elements, while the script shows the intended use of d3.select and d3.append for dynamic manipulation, though it is not executed due to the commented syntax.

D3: Drawing SVGs

This example demonstrates how to create basic SVG shapes with D3.js by rendering five circles of increasing radius. The code uses D3’s data join pattern, calling `selectAll`, `data`, `enter`, and `append` to bind an array of five numbers to circle elements. Each circle’s x-position is calculated from its index, its radius from the bound data value, and its fill, stroke, and stroke-width are set accordingly. The static SVG is 500 pixels wide and 50 pixels tall, with all circles vertically centered.

Introduction to D3

This example demonstrates basic vector graphics construction with D3 version 7, using d3.select to append SVG shapes (circle, rect, and line) to the document body within a 500×500 coordinate space. The code loads D3 from UNPKG and directly manipulates attributes such as cx, cy, r, fill, width, height, and line endpoints, though it notably contains attribute typos (e.g., `widht` instead of `width`) and redefinitions that the renderer would interpret. The visualization serves as a minimal introduction to D3’s SVG API, highlighting how to create and stylize geometric primitives without data binding or interaction.

d3

This example demonstrates a minimal D3.js starter template that displays a single large circle in an SVG container. The visualization shows a basic geometric shape centered within a 700x500 pixel viewport, using a 200-pixel radius circle positioned at explicit x and y coordinates. The code initializes the SVG element via `d3.select` and appends the circle using the `append` method with chained `attr` calls to set its dimensions. The page title is updated dynamically through D3's selection and text methods. The visualization is rendered with SVG and styled with a custom CSS file affecting font size and family choices.

SVG Fundamental

This example demonstrates the foundational structure of an SVG-based visualization using D3.js v3. It begins with an empty HTML document that includes a reference to the D3 library, highlighting the basic setup required for creating data-driven graphics. The visualization shows how D3’s selection and append methods can build and manipulate SVG elements, though the trigger for rendering is not explicitly coded. The author, Smpeak001, focuses on the essential scaffold—an `<svg>` container and minimal styling—rather than a full dataset. It serves as a starting point for learning how D3 binds data to scalable vector graphics for interactive charts or maps.

D3.js

This example shows a bare SVG element sized 960 by 500 pixels, with no visible chart or data rendered from the provided CSV of country populations. The page loads D3 v5, imports `select` and `csv` from the library, and sets width and height variables from the SVG attributes, but the JavaScript stops there without drawing marks or binding data. The stylesheet applies a 13em font size to the body, affecting the page’s text layout. Rendering is purely SVG, with no axes, scales, or population values displayed.

D3 SVG

This example demonstrates basic SVG shapes rendered with D3.js, showing how static geometric elements can be drawn directly in a web page. It displays a blue circle and a rectangular outline with a stroke, positioned at fixed coordinates within an SVG canvas of 500 by 960 pixels. The code uses the D3.js library to construct the SVG container and its child elements, with circle and rect tags defining the visual properties. The rendering approach relies on D3’s SVG manipulation capabilities, though no data binding or dynamic updates occur, as the shapes are hardcoded in the HTML structure.
