This example demonstrates four fundamental techniques for creating DOM elements with D3.js v5, adapted from a v3-era cookbook. It shows method chaining to append divs and paragraphs, the `selection.call` function to encapsulate creation logic, a custom initializer function passed to `.call()`, and finally, dynamic SVG element creation with bound data. The code uses `d3.select` (a corrected form of `d3.select`) and the enter/append pattern to build a simple bar-like structure of labeled boxes.

This example demonstrates how to build reusable chart components in D3.js v5 by wrapping SVG creation logic in a function that can be called on a selection, following the pattern from Pro D3.js. The page shows two containers where an array of three string values is bound to div elements, then each div uses `selection.call()` with a custom `chart2` function to append an SVG element with a white background rectangle. The code highlights the transition from earlier D3 versions, using `data()`, `enter()`, and `append()` to manage the enter selection, with the second example adding nested divs and SVG elements.

MasteringD3js_Ch2 pt2

A D3.js v5 barcode chart built from a step-by-step refactoring of a v3 example. The visualization uses an SVG-based, closure-encapsulated charting function that renders a horizontal strip of vertical bars representing time-based data, with accessor methods (`chart.width`, `chart.height`, `chart.margin`) and a date accessor to set the temporal interval. The code demonstrates progressive enhancements across six chart versions, transitioning from raw selections (`d3.select`) to data joins and SVG initialization, with the dataset bound through `.data()` and rendered via `.enter().append()`.

MasteringD3js_ReuseProD3_Ch2 pt2.2a

Reusable D3 chart functions build SVG bar charts from an array of four string values, rendering yellow background rectangles with blue bars in separate containers for two chart instances. The code demonstrates the transition from D3 v3 to v5 while implementing the ProD3 reusable chart pattern, using `selection.each`, `selection.enter`, and `selection.call` to structure modular chart components.

MasteringD3js_Ch4.1

This example demonstrates three stages of building an interactive slider control using D3.js v5. It first shows a draggable circle using the `d3.drag` behavior, then constructs a reusable slider component with a linear scale and drag handler, and finally binds the slider to update data. The SVG rendering approach uses `d3.select` and `d3.scaleLinear` to map domain values to pixel positions, with circles and lines as visual elements. The code reflects a migration from v3 to v5, adapting drag event handling from the older API.

D3_CookBook_Ch 1 & 2

This example demonstrates introductory D3.js and JavaScript concepts from the D3 Cook Book, showing how to create reusable widget functions and manipulate DOM elements. It uses d3.select and d3.selectAll to target paragraphs and divisions, applying CSS classes to render colored boxes with red and blue backgrounds. The code also illustrates functional JavaScript patterns through a SimpleWidget constructor that chains methods like _headline and _description to build custom components. Data binding is shown through d3's .each method to append text elements within selected paragraphs.

D3 Learning

This example demonstrates fundamental D3.js data binding and selection techniques through a simple bar chart. It loads an array of numeric values and maps them to SVG rectangles, with the height of each bar proportional to its corresponding data point. The code uses `d3.select` and `d3.selectAll` to manipulate DOM elements, while the `.data()`, `.enter()`, and `.append()` methods create the visual bars from the dataset. Additionally, it shows how to modify text content and styles on headings and paragraphs, illustrating both static selection and dynamic data-driven rendering in React.

MasteringD3js_ReuseProD3_Ch2 pt2.2d

This example demonstrates adding and removing data in D3.js v5 bar code charts using a reusable module pattern adapted from the ProD3.js approach. The visualization generates random time-based data using an exponential distribution and renders it as horizontal bar codes within SVG containers. It includes interactive buttons that trigger data updates, showing how D3 selections and data joins handle dynamic changes. The code uses d3.scaleTime for time scaling, d3.max/d3.min for domain calculations, and d3.timeDay for time intervals, while the barcode elements are drawn as SVG rects.

MasteringD3js_ReuseProD3_Ch2 pt2.2b

This example demonstrates a reusable bar-code chart pattern built with D3.js v5, displaying multiple rows of temporal data as horizontal barcode-like visualizations. Each row represents a distinct data series with randomly generated date intervals using an exponential distribution. The code implements a modular chart function that creates SVG elements within styled containers, using `d3.scaleTime()` to map date ranges to pixel positions. The example highlights the transition from D3 v3 to v5 practices, showcasing proper data binding, scale construction, and container management in a reusable component pattern.
