Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data using D3 v5 and asynchronous JavaScript. It fetches a dataset of CSS named colors from a GitHub gist and displays summary statistics, including file size in kilobytes, row count, and column count, in a large text format. The code uses `d3.csv` with promise-based `.then()` handling, as well as commented alternatives using `fetch`, `async`/`await`, and `d3.csvParse`. It also references older callback-based "pyramid of doom" patterns for comparison.

This example demonstrates how to load and parse CSV data using D3 and the Fetch API. It fetches a list of CSS named colors from a GitHub Gist and displays a summary of that dataset: the file size in kilobytes, the number of rows, and the number of columns. The code highlights two approaches: using `d3.csv` to fetch and parse directly, and an alternative method that uses `fetch` with `async`/`await` alongside `d3.csvParse`. A commented-out section shows an older "pyramid of doom" pattern. The results are rendered as large text in an HTML `<pre>` element, with a font size set via CSS.

This example demonstrates how to load and parse CSV data using D3 v5 and the Fetch API. It displays the file size in kilobytes, the number of rows, and the number of columns from a dataset of CSS named colors. The code uses `d3.csv` for direct parsing and a commented alternative with `fetchText` and `d3.csvParse`. It highlights both the promise-based `then` pattern and the async/await approach, while avoiding the "pyramid of doom" by chaining promises.

This example demonstrates how to load and parse CSV data using D3 v5 and native browser APIs. It fetches a dataset of CSS named colors from a GitHub gist and displays the file size in kilobytes, row count, and column count in a large text element. The primary implementation uses `d3.csv` with a promise-based `.then()` callback, while commented-out alternatives show the same task using `fetch`, `async/await`, and `d3.csvParse`. The code also includes a commented "pyramid of doom" example illustrating nested promise callbacks.

This example demonstrates how to load and parse CSV data using D3 v5. It fetches a CSS Named Colors dataset from a GitHub gist and displays its size (in kilobytes), row count, and column count in a large text area. The primary implementation uses `d3.csv` with promise handling, while commented-out alternatives show equivalent approaches using `fetch` with `async`/`await` and `d3.csvParse`. The visualization is minimal, focusing on data loading mechanics rather than graphical representation.

This example demonstrates how to load and parse CSV data using D3 v5’s `d3.csv` method, which returns a promise. It fetches a dataset of CSS named colors from a GitHub gist and displays the file size in kilobytes, the number of rows, and the number of columns in large text. The code also includes commented-out alternatives using `fetch`, `async`/`await`, and `d3.csvParse` for comparison, highlighting different asynchronous patterns for handling data loading in a React-based visualization context.

This example demonstrates the process of loading and parsing CSV data using the D3 v5 library. The visualization fetches a CSS Named Colors dataset from a GitHub gist, then retrieves the raw text content through the Fetch API and `response.text()`. The code uses an async/await pattern within a `fetchText` function to handle the asynchronous data loading, ultimately logging the parsed text to the console. The example serves as a straightforward demonstration of data acquisition without any rendering or graphical output.
