Forked from Loading and Parsing CSV Data

This example demonstrates two approaches to loading remote data in a browser using D3 v5 and React. It fetches JSON from NOAA’s estimated planetary K-index service, logging the parsed array to the console via `d3.json().then()`. An alternate, commented-out path shows using `fetch` with `async`/`await`, parsing CSV text with `d3.csvParse`, and displaying file size, row count, and column count in a large `<pre>` element. The code highlights modern promise-based data loading versus older callback patterns.

This example demonstrates how to load and parse data from an external JSON API, specifically the NOAA solar-cycle prediction feed, using `d3.json` within a React framework. The page displays the parsed data in the browser console, though a commented-out alternative using `fetch`, `async`/`await`, and `d3.csvParse` shows how to compute and render file size, row count, and column count into an HTML `<pre>` element. The code runs with D3 v5 and includes commented variations highlighting different asynchronous patterns, such as a callback-based “pyramid of doom” approach.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote source using D3 v5. It displays the file size in kilobytes, the number of data rows, and the number of columns derived from the CSS Named Colors dataset. The primary implementation uses `d3.csv` with a promise to fetch and parse the data, while commented-out alternatives show `fetch` with `async`/`await` and `d3.csvParse`. A large `pre` element renders the summary statistics as text.

Fork of Loading and Parsing CSV Data

This example demonstrates loading and parsing CSV data from a remote URL using D3 v5 and React. It displays the size of the dataset in kilobytes, the number of rows, and the number of columns in a large text format. The code uses `d3.csv` to fetch and parse the data, alongside an alternative approach using the Fetch API with async/await and `d3.csvParse`. The data source is a CSV file containing CSS named colors hosted on GitHub Gist.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data using D3 v5 and React. It fetches a remote CSV file containing CSS named colors and displays the dataset’s size in kilobytes, row count, and column count in a large text block. The primary approach uses `d3.csv` with a Promise-based `.then()` callback, while commented-out code illustrates alternative methods using `fetch` with `async/await` and `d3.csvParse`. The data source is a GitHub Gist hosted CSV file.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data in a React-friendly environment using D3 v5. It fetches a remote dataset of CSS named colors via `d3.csv` and displays summary statistics—file size in kilobytes, row count, and column count—in a large HTML `<pre>` element. The code also includes commented alternatives using `fetch` with async/await and `d3.csvParse` for comparison. The visualization is text-based, showing raw data metrics rather than graphical rendering, and highlights both direct CSV parsing and manual text fetching approaches.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL, displaying summary statistics about the dataset in a large, readable text format. It uses the `d3.csv` method to fetch and parse the CSS Named Colors dataset, then reports the number of rows, columns, and approximate file size in kilobytes. The code highlights both a promise-based approach with `d3.csv` and an alternative commented-out implementation using `fetch` with async/await and `d3.csvParse`, showcasing different ways to handle data loading in D3 v5 within a React framework.

Fork of Loading and Parsing CSV Data

This example demonstrates the loading and parsing of CSV data from a remote URL, displaying the file size, row count, and column count as plain text. The code primarily uses D3.js version 5’s built-in `d3.csv` method, which returns a promise that resolves to parsed data. An alternative commented-out approach uses the Fetch API with `async`/`await` and `d3.csvParse` for manual parsing. The data comes from a gist containing CSS named colors, and the results appear in a large-font `<pre>` element.
