This example demonstrates how to load and parse CSV data in a web browser. It fetches a dataset of CSS named colors from a GitHub Gist and displays summary statistics—file size in kilobytes, row count, and column count—in large text. The primary implementation uses d3.csv to fetch and parse the data asynchronously, while commented-out alternatives show the same task using fetch with async/await and d3.csvParse, including a nested promise “pyramid of doom” pattern. The visualization itself is minimal, focusing purely on the data-loading workflow with d3.v5 in a React-free HTML page.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data in a web browser, displaying the dataset's size in kilobytes, row count, and column count as large text. The code uses the D3.js library (version 5) with its `d3.csv` method to fetch and parse a CSV file containing CSS named colors from a GitHub gist. It also includes commented-out alternative approaches using the Fetch API with async/await and `d3.csvParse`. The visualization is built within a React framework and relies on D3's promise-based data loading to handle the asynchronous data retrieval.

Fork of Loading and Parsing CSV Data

This example demonstrates the basic mechanics of loading and parsing CSV data in a web browser, displaying the file size, row count, and column count of the CSS Named Colors dataset from a GitHub gist. The primary implementation uses D3 v5’s `d3.csv` method with a promise chain, while commented-out alternatives show the same task using `fetch` with `async`/`await` and `d3.csvParse`, plus a nested promise “pyramid of doom” pattern. The rendered output is plain text in a large `<pre>` element, with a React-based counterpart provided in `index.js` using the `useEffect` hook to load data asynchronously.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse a CSV file containing CSS Named Colors using D3 v5 and React. The page displays a summary of the dataset—its size in kilobytes, number of rows, and number of columns—in a large text element. The primary implementation uses `d3.csv` with promises, while commented-out alternatives show `fetch` with `async`/`await` and `d3.csvParse`, plus a nested promise structure illustrating the "pyramid of doom." The data comes from a GitHub gist hosted CSV file.

Fork of Loading and Parsing CSV Data

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.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data using D3 v5 within a React framework. It fetches a dataset of CSS named colors and displays summary statistics—file size in kilobytes, row count, and column count—in large, preformatted text. The code uses the Fetch API with async/await and d3.csvParse, though the active implementation is commented out, leaving only the rendered message container. It contrasts this approach with a commented-out "pyramid of doom" nested promise pattern.

This example demonstrates how to load and parse CSV data using D3 v5 within a React framework. It fetches a dataset of CSS named colors from a GitHub gist and displays summary statistics—file size in kilobytes, row count, and column count—in a large HTML `<pre>` element. The primary implementation uses the `d3.csv` method, which returns a promise, while commented-out alternatives show the same task with `fetch` and `async`/`await` syntax, alongside `d3.csvParse` for manual parsing. The code also includes a commented “pyramid of doom” pattern for comparison.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data, displaying a summary of the dataset’s size in kilobytes, row count, and column count. It fetches CSS named colors from a GitHub gist and processes the data using `d3.csv` with promises in D3 v5. The code includes commented alternatives using `fetch`, `async`/`await`, and `d3.csvParse`, illustrating different asynchronous approaches. The result updates a plain text element, showing the parsed data’s dimensions without any chart rendering.

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 dataset of CSS Named Colors from a GitHub gist and displays the file size, row count, and column count in a large text block. The primary implementation uses `d3.csv` with a promise, while commented alternatives show equivalent approaches using `fetch` with `async`/`await` and `d3.csvParse`, highlighting different asynchronous patterns. The interface presents the parsed data summary without any visual chart.
