Forked from Marks and Channels

This example demonstrates six fundamental marks and channels in D3, each rendered as a separate SVG panel using `d3.select`, `selection.join`, and `selection.each`. It sequentially applies positional encodings (x, y), size (radius), bar length, shape via `d3.symbol` with contrasting symbols, and hue using `d3.schemeCategory10` color scheme. Each panel uses static synthetic data—an array [0,1,2,3,4]—and explicit pixel mappings for scales, with circles, rectangles, and paths drawn as SVG elements. The main `index.js` orchestrates multiple modules, importing named functions and binding them to data-driven SVG containers.

AI-generated description

A demonstration of basic D3 usage to implement the concept of Marks and Channels. Includes usage of:

  • Point Marks by X, Y, Size
  • Line mark varying in length
  • Scaling factors
  • SVG Rectangles
  • selection.each()
  • SVG Path Elements
  • d3.symbol()
  • SVG attributes transform and fill
  • D3 Color Schemes
  • JavaScript Modules

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.

Marks and Channels

This example demonstrates the core visualization concept of marks and channels by rendering five separate SVG panels. Each panel uses the same dataset of five values to illustrate different visual encodings: X position, Y position, circle size, bar length, shape variety, and color hue. The code leverages the D3.js library, specifically using `selection.each()` to iterate over the panel generator functions. It applies D3’s `schemeCategory10` for categorical colors, custom `symbol()` paths for varied shapes, and sets positions and dimensions via `attr()` calls. The visualization serves as a clear, side-by-side comparison of how different channels encode identical data.

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

This visualization demonstrates the concept of marks and channels in data visualization, showcasing how different visual encodings represent the same dataset. Using D3 version 7.8.5, six separate SVG panels each apply a distinct channel—X position, Y position, size, length, shape, and hue (color)—to encode the data points [0, 1, 2, 3, 4]. The code leverages D3’s `selection.each()` to iterate through these channel modules, `d3.symbol()` for path generation, and `schemeCategory10` from D3 for color mapping. It also utilizes SVG rectangles, circles, and path elements with `transform` and `fill` attributes.

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.

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

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`.

Fork of Marks and Channels

This example illustrates the fundamental concept of marks and channels in data visualization by generating six separate SVG plots, each encoding the same array of five integers using a different visual channel: x position, y position, circle size, bar length, shape, and hue. The code leverages D3 v7 modules including `selection.join()`, `d3.symbol()` for generating shape paths, and the `schemeCategory10` color scheme. It demonstrates modular JavaScript by importing distinct functions like `xPosition` and `size` from separate files, with each function applying a unique scaling factor to the data. The rendered output shows how identical data can be represented through varied visual attributes.
