Six small multiples demonstrate how different visual channels encode the same five-point dataset. Each panel maps a value to a different mark property: x-position, y-position, rect length, circle area, symbol shape, and categorical color via `schemeCategory10`. Panels are rendered as separate SVGs using `select` and `join` from the v7 D3 API, with each channel defined in its own module (`xPosition.js`, `length.js`, `hue.js`, etc.) and composed in `viz.js`.

Marks and Channels

This visualization demonstrates the concept of marks and channels, showing how position (x and y), size, length, shape, and hue encode data in separate SVG panels. Each panel uses D3 joins to bind the array [0, 1, 2, 3, 4] to circle, rect, and path elements, with attributes like `cx`, `cy`, `r`, `height`, and `fill` set via scale-like functions. The code imports from the `d3` module, using `schemeCategory10` for color, `symbol()` and `symbolsFill` for shapes, and `selection.each()` to dispatch each mark function.

Marks and Channels

A small multiples grid of five D3.js plots demonstrates how the same dataset—the numbers zero through four—can be encoded through different visual channels. Each panel isolates a single mark or channel: x-position, y-position, size, length, shape, and hue, using circles, rectangles, and paths. The code uses D3’s selection and join API within a custom viz.js orchestrator, rendering SVG directly. Shape encoding leverages d3.symbol() with symbolsFill, while hue applies schemeCategory10.

This example visualizes the fundamental concept of marks and channels in data visualization, using six small multiples to demonstrate how the same dataset can be encoded through position, size, length, shape, and color. Each SVG panel uses a distinct D3 encoding, such as circles scaled by radius or symbols generated via `d3.symbol()`. The code relies on D3's selection API with `.join()` and `.each()` to create and update the graphics, along with color schemes like `schemeCategory10` and JavaScript modules to organize the distinct channel implementations.

Marks and Channels

This example illustrates the fundamental concept of encoding data through different visual channels—position, length, size, shape, and color—using D3.js. Five distinct marks, each with a static array of five data points, are rendered in separate panels to demonstrate how changing a single channel alters the representation of the same data. The code uses the D3 `select`, `join`, and `attr` API to build SVG circles, rectangles, and paths, applying `schemeCategory10` for categorical colors and custom functions for scaling and positioning.

Marks and Channels

This example demonstrates D3 marks and channels by rendering six small multiples, each using a different visual channel—x position, y position, size, length, shape, and hue—to encode the same array `[0,1,2,3,4]`. Each SVG is generated using D3’s `select`, `selectAll`, and `join` API, with channels implemented via attribute callbacks like `attr("cx", ...)` and `attr("r", ...)`. It also uses `d3.symbol()` for generating SVG path symbols, `d3.schemeCategory10` for color, and the `selection.each()` method to apply each channel’s function. The code uses the `d3` module from a local script, relying on `d3.select`, `d3.selectAll`, and `d3.join` to build and update the SVG elements.

Fork of Marks and Channels

Five small multiples panels illustrate core D3 marks and channels. Each panel encodes the same five-value array through a different visual variable: x position, y position, size, length (bar height), shape (using `d3.symbol` and `symbolsFill`), and hue (using `schemeCategory10`). The `viz.js` file binds an array of functions to SVG elements via `selection.join`, applying each function to render its panel in separate SVG containers.

Marks and Channels_NH

This example demonstrates how different visual channels can encode the same quantitative data. Seven circles are horizontally positioned by value, with their size, position, and color all reflecting the data. The visualization cycles through three distinct encoding methods: length, where bars of varying height represent values; size, where circles use square-root scaling for area; and hue, which assigns categorical colors from `d3.schemeCategory10`. Built with D3 v7, it uses data joins and selection methods to render the SVG marks.

D3 Marks & Channels

This example demonstrates five fundamental D3 marks and encoding channels using a small array of numbers. It shows circles positioned along the x-axis and y-axis, circles scaled by area, rectangles representing length, and symbols displaying different shapes. The visualization uses D3 v7 with the `select`, `symbol`, and `symbolsFill` APIs to bind data and generate SVG elements. The data is a simple fixed set of integers, rendered as multiple separate SVG canvases, each focusing on a distinct mark and channel combination.
