A circular progress meter displays the loading status of a remote JSON file from the GitHub API, using a black foreground arc over a gray background ring. As the data streams in, the arc's angle and percentage text update smoothly via `d3.transition()` and an interpolated `tween` function, driven by the progress event from `d3.json`. The code relies on the deprecated `d3.svg.arc()` and `d3.event.loaded` pattern, and upon completion, the entire meter scales down and disappears with a delayed `transition.attr`.

Progress Events

This example visualizes the progress of an asynchronous request as a circular gauge with a dark foreground arc filling a gray background track, alongside a percentage label. The data is fetched from a GitHub API endpoint, and the gauge animates smoothly by interpolating progress values. The code uses `d3.json` to create a request object, registers a "progress" event listener with `.on`, and updates the arc by setting its end angle through `arc.endAngle`. The process runs in SVG, with animation handled via `d3.transition` and `d3.interpolate`. Once the request completes, the gauge scales down via a transition.

A gauge in D3.js with gradient generator

This gauge visualization displays six semicircular arcs around a central value readout, each shaded with a gradient that transitions between colors to represent different battery and power states. The code uses D3.js v5’s `arc` generator and `transition` method, building linear gradients via `svg.append('defs')` with `linearGradient` elements positioned using trigonometric calculations. A dark slate indicator arc and a white percentage text label update smoothly, while the SVG canvas is statically sized at 900×500 pixels.

d3Edge_V5-dataLoading

This example demonstrates a modular data-loading pattern for D3.js v5, showing how to decouple CSV and GeoJSON fetching from chart rendering. It defines a `dataManager` module that uses `d3.csv` with async/await and `d3.json` to load external files, applying custom cleaning functions to the CSV data. The module dispatches custom events (`dataLoading`, `dataReady`) via `d3.dispatch`, and uses a custom replacement for the removed `d3.rebind` to expose event handling. The page displays a loading message until data arrives, then instructs users to inspect the cleaned data via `getCleanedData()`.

d3Edge_V5-dataLoading-v0.3

This example demonstrates a custom data-loading module for D3 v5 that manages asynchronous CSV and GeoJSON requests through a dispatch system. It shows how to load Zurich transit delay data from a remote CSV file, clean the rows by parsing timestamps and coordinates, and expose the processed dataset via a public API. The code uses `d3.csv`, `d3.json`, and a `d3.dispatch` event bus to signal loading progress and readiness, with a placeholder page indicating when data is available for console inspection.

Simple D3 Percentage Gauge Responsive

A responsive percentage gauge displays a semicircular progress arc with a live numeric percentage label, updating automatically through a timed sequence of sample value pairs. The visualization uses D3 v4’s `d3.arc` and `d3.arc` with `startAngle` and `endAngle` to construct the background and foreground arcs, while SVG text shows the computed percentage. The gauge resizes based on the viewport width using jQuery, and its width, radius, and font size scale proportionally. Animation cycles through hardcoded test values, though the update itself is not animated, only redrawn. The rendering relies on SVG paths and standard D3 selection methods.

d3Edge_V5-dataLoading-v0.4

This example demonstrates a modular data-loading system for D3.js v5, built around a custom dispatch event manager. It loads a CSV file of Zurich transit delay data and a separate TopoJSON geographic file, applying a cleaning function to parse timestamps and coordinates. The code uses asynchronous `d3.csv` and `d3.json` loading with custom `dataLoading`, `dataReady`, and `geoReady` events, and exposes methods like `getCleanedData()` for console inspection. The visualization itself remains a placeholder, showing a loading message and instructions while the data pipeline runs.

d3EdgeReusable_BarChartWithTransitions-Simple2.3_v5

This example demonstrates a reusable bar chart module built with D3 v5, following the reusable chart pattern from *Developing a D3.js Edge*. Four separate bar charts render random datasets, each transitioning smoothly between data states using `d3.transition` with a bounce easing. The chart uses `d3.scaleBand` and `d3.scaleLinear` for axes, with `d3.axisBottom` and `d3.axisLeft` for rendering. An SVG container manages enter, update, and exit selections for the bars, and a custom event dispatcher supports hover interactions.

Simple D3 Percentage Gauge

This example displays a rotating set of percentage gauges, cycling through seven predefined value pairs to show the proportion of a lower to an upper total. It demonstrates how a semicircular gauge can be built with D3 v4 and SVG, using `d3.arc` to define the background track and the colored progress arc, with a red fill indicating the current percentage. The gauge updates every second via `setInterval`, and the center text shows the rounded percentage. The code relies on jQuery for document readiness, while D3 handles the rendering, and the animation is a simple replacement of the SVG elements rather than a transition.
