Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse a CSV dataset containing CSS named colors using D3 v5. The visualization displays basic statistics about the loaded data—its file size, row count, and column count—in large text. The code primarily uses the `d3.csv` method with a promise to fetch and parse the remote CSV file. An alternative approach using the Fetch API with `async` and `await` is also shown in commented code, alongside a demonstration of the older "pyramid of doom" callback pattern.

This example demonstrates how to load and parse CSV data using D3 version 5, displaying summary statistics about the CSS Named Colors dataset from a GitHub gist. The visualization shows three key metrics: the file size in kilobytes, the number of rows, and the number of columns, rendered in large text. It utilizes D3’s `d3.csv` method with Promise-based asynchronous loading, alongside commented-out alternatives using the Fetch API with `async`/`await` and `d3.csvParse`. The code also includes a commented "pyramid of doom" example comparing older nested callback patterns with modern approaches.

This example demonstrates loading and parsing CSV data by displaying key statistics about the CSS Named Colors dataset, including file size, row count, and column count. It uses d3.csv to fetch the remote CSV file and returns a promise that resolves with the parsed data. The code also includes commented-out alternatives using fetch with async/await and d3.csvParse, as well as a nested promise “pyramid of doom” pattern, to illustrate different approaches to asynchronous data loading in D3 v5.

This example loads CSS named colors from a CSV file hosted on GitHub and displays a summary of the dataset as text. It uses D3 v5’s `d3.csv` method to fetch and parse the data, then reports the file size in kilobytes, the number of rows, and the number of columns. The code also includes commented-out alternatives using the Fetch API with async/await and `d3.csvParse`, as well as a nested promise “pyramid of doom” pattern for comparison. The rendered output is a simple `<pre>` element with large monospaced text.

This example displays summary statistics about a CSV dataset of CSS named colors, including file size in kilobytes, row count, and column count. The visualization is minimal—just text in a large font—but demonstrates three approaches to loading and parsing CSV data using D3 v5 and modern JavaScript. The active code uses `d3.csv` with a promise, while commented-out alternatives show `fetch` with `async`/`await` and `d3.csvParse`, as well as a nested promise structure often called the “pyramid of doom.” The data comes from a GitHub gist of named colors.

The rendered output is a simple text summary within a `pre` element.

This example demonstrates how to load and parse a CSV file containing CSS named colors, displaying summary statistics about the dataset in a large text element. The code uses D3 v5’s `d3.csv` method to fetch the remote data asynchronously and then computes the file size in kilobytes, row count, and column count using `d3.csvFormat` and the parsed array’s properties. Alternative approaches using `fetch` with `async`/`await` and `d3.csvParse` are also included as commented-out code, along with a nested-promise “pyramid of doom” example for comparison.
