This example demonstrates a minimal data-loading and parsing workflow using D3 v5. It reads a CSV file, filters out the first three lines of metadata, and parses the remaining rows into a JavaScript array of objects. The code uses `d3.text` to fetch the file and `d3.csvParse` to convert the cleaned string into structured data. A console log then prints the parsed result, but no visualization or chart is rendered; the focus is purely on data ingestion and preprocessing. The source is a local `data.csv` file, and the approach highlights D3’s utility for handling tabular data before any graphical encoding begins.

This example loads a live dataset from the UN OCHA Pooled Fund API via `d3.csv` and logs the parsed rows to the browser console. It demonstrates the basic pattern of fetching external CSV data and inspecting its structure, but the page itself renders no visual output—only a static heading. The code relies on the standard D3 v5 fetch-and-parse pipeline, showing how to retrieve tabular data asynchronously and handle the returned promise with `.then()`. The example serves as a minimal starter template for debugging data before building a chart.

This example demonstrates loading two separate CSV files with D3 v5 and logging their contents to the browser console. It shows how to use promises with `d3.csv` to sequentially load multiple datasets, with each file’s data converted to JSON objects and printed for inspection. The page itself renders no visual output, serving purely as a test harness for asynchronous data fetching. It relies on the native Fetch API via the promise-polyfill and D3’s CSV parsing, and includes a minimal HTML structure with a heading and script. The data sources are `file1.csv` and `file2.csv`, each containing simple numeric columns.

This example demonstrates how to load and parse two separate CSV files using D3.js v5, then combine them with a Promise.all to log their contents to the browser console. It shows the process of handling multiple asynchronous data sources and verifying their successful retrieval. The code uses `d3.csv` to fetch each file and `Promise.all` to wait for both to resolve, while also loading the Fetch API and promise polyfills for broader browser support. The visualization itself is minimal, with the output appearing solely as console messages rather than rendered graphics.

This example demonstrates how to load and inspect two separate CSV files using Promises in D3 v5. The code uses `d3.csv` to fetch `file1.csv` and `file2.csv`, then combines them with `Promise.all` to log the parsed data as JSON objects to the browser console. It explicitly shows the structure of each row, revealing fields like `foo`, `bar`, and `baz` with numeric values. The page itself displays only a static heading, while all observable behavior occurs in the console, making the data-loading pipeline the core focus.

This example demonstrates how to load and combine multiple CSV files using D3 v5’s Promise API. It shows the parsed contents of two separate CSV files (file1.csv and file2.csv) logged to the browser console after both have loaded successfully. The code uses `d3.csv()` to fetch each file and `Promise.all()` to wait for both requests before logging the resulting arrays of objects. The page displays a simple heading and relies entirely on console output for visualization, with no graphical rendering. The data source is the two CSV files, and the approach highlights asynchronous data loading in D3.

CSV

This example demonstrates a bare-bones CSV parsing workflow using D3 v6. It fetches a remote text file containing CSS color data from a GitHub gist, then parses it with `d3.csvParse` to produce a JavaScript array of objects. The parsed data is logged to the browser console, while the container element remains empty, as the code does not yet render any visualization. The page itself is a minimal HTML document that loads D3 from a CDN and relies on the native Fetch API to retrieve the external data source.

This example shows a small dataset of timestamped numeric values being loaded and parsed from an external JSON file. It demonstrates a robust data-cleaning technique where the raw text is first altered to replace any unquoted `-Infinity` values with quoted strings, then parsed with a custom reviver function that converts those strings back into JavaScript’s native `-Infinity` number. The visualization itself is minimal—the code only logs the resulting parsed array to the console, with no visual elements drawn. It relies on D3 v5’s `d3.text` method to fetch the file and `JSON.parse` with a reviver callback to handle edge-case numeric literals. The data originates from a gist, with the structure showing two parallel numeric columns per timestamp.

Loading and Parsing CSV Data

This example demonstrates how to load and parse remote CSV data, displaying basic dataset statistics as plain text. It fetches a raw CSV file from a GitHub gist using the Fetch API, then parses the text with `d3.csvParse` to produce an array of objects and column metadata. The visualization shows the file size in kilobytes, row count, and column count in a simple `<pre>` element. The code uses D3 v7’s parsing utilities alongside native JavaScript async functions, without any graphical rendering.
