This example loads a JSON file containing a bus route's path and station data using D3's `d3.json` function. It demonstrates how to fetch and parse external JSON data within a D3 v4 visualization, logging the parsed `lineStrings` array and its length to the console. The visualization reads from `outbound.json`, which includes geographic coordinates for a London bus route, but does not render any graphical output.

This example loads a Transport for London bus route JSON file and logs it to the browser console, displaying raw route and station data for the Number 24 bus without any visual rendering. It uses the `d3.json` method from d3.v4 to asynchronously fetch `outbound.json`, which contains geographical line coordinates and stop information. The code sets up a full-screen HTML body and prepares for potential future data visualization, though currently it only outputs the parsed data object for inspection.

Read in JSON department files

This example demonstrates how to load and integrate data from multiple JSON files using D3.js v5. It reads two datasets—department names and course pathways—via `Promise.all` and `d3.json`, then logs both to the console. The visualization renders a list of course names as plain text paragraphs, appended to the body with `d3.select("body").selectAll("p")` and `.data(pathwaysData)`. The code highlights asynchronous data loading and simple data binding without any graphical marks or scales.

D3 test

This example visualizes a historical route from a GeoJSON file, displaying daily segments as dashed black polylines over a light blue graticule-filled map. The code uses D3 v5 with an SVG rendering approach and a Mercator projection configured via `d3.geoMercator()`. It loads coastline and route data with `d3.json()`, then binds the features to SVG paths using `d3.geoPath()`. The graticule is generated with `d3.geoGraticule()`. The visualization clearly shows the path’s progression across the mapped region, with each day’s travel distinguished by styling properties like stroke dasharray.

Public Transport Journeys by Type of Transport London Data

This example loads a CSV file of London public transport journey data from the London Data Store and prints a text-only summary of the dataset. The visualization directly displays the number of rows, columns, and kilobytes of the CSV, followed by the first 10 rows as a JSON string. Using the `d3.csv` function to parse the data, the program applies `d3.select` to append `<pre>` elements to the body, showing the raw metadata and sample records. The page features a green-on-black terminal aesthetic defined by custom CSS.

Fork of Graph to london

This example visualizes London Underground stations as an interactive scatterplot, with each station positioned by its longitude and latitude coordinates from a JSON dataset. The visualization includes zoom and pan abilities, longitude and latitude axes, and station labels. The code uses D3 v4 with d3.scaleLinear for coordinate mapping, d3.axisBottom and d3.axisLeft for grid lines, and d3.zoom for user interaction. Stations are rendered as orange SVG circles on a white background, with a toggle button to switch to a map view.

HTML Starter

This example loads a JSON file containing student attendance records and logs it to the browser console using d3.json. The page displays a bare minimum HTML structure with a large text element, though no visual encoding of the data is rendered. It uses d3.v5 to fetch the external att_data.json file, which includes fields such as module code, attendance status, and timestamps. The code demonstrates the simplest possible integration of D3 into a React-free HTML page.

parsing json data

This example demonstrates how to load and parse a single JSON record containing air quality monitoring data using D3’s `json()` method within a React component. The visualization shows the raw fields from the data file, including location details, ozone measurements, and AQI values, though no chart is rendered. The code uses React hooks (`useState`, `useEffect`) to fetch the data asynchronously and store it in state, with D3 v6 handling the JSON parsing via `d3.json`. The interface remains a blank page as the parsed data is only logged to the console.

test getting data from json format

This example builds a basic force-directed graph from hardcoded JSON-like link data, mapping source and target names into node objects. It renders SVG lines for links and grouped circles with text labels for nodes, using D3 v6 and legacy v3. The code demonstrates data binding and entry selection, though it lacks simulation physics and mouse interaction despite the title suggesting JSON retrieval.
