Forked from Loading and Parsing CSV Data

This example demonstrates the use of D3 v5's `d3.csv` method to load a CSV dataset containing CSS Named Colors from a remote URL, then parses and displays summary statistics about the data. The page renders the file size in kilobytes, row count, and column count in large text within a `<pre>` element. The code highlights the modern asynchronous pattern with promises via `.then()`, while commented-out alternatives show `fetch` with `async`/`await` and a nested "pyramid of doom" approach for comparison.

how to fetch data

This example demonstrates three different ways to load a CSV file, using both the Fetch API and D3’s built-in `d3.csv` and `d3.csvParse` functions. It fetches a CSV 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 a large `<pre>` element. The code contrasts asynchronous promise-based fetching with the equivalent `d3.csv` shorthand, and includes an unused `async`/`await` function. The visualization itself is purely textual, providing metadata about the loaded dataset.

Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL using D3 v5 and the Fetch API. It displays the file size in kilobytes, row count, and column count of the CSS named colors dataset in large text. The primary implementation uses `d3.csv` with a promise, while commented-out alternatives show `fetch` with `async`/`await` and a nested callback approach. The code visually emphasizes the simplicity of modern asynchronous data loading compared to older patterns.

Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data using D3.js v5. It fetches a remote dataset of CSS named colors and displays key statistics about the data, including the number of columns, rows, and file size in kilobytes. The primary approach uses `d3.csv` to directly fetch and parse the CSV, while commented-out code shows an alternative using the Fetch API with `async/await` and `d3.csvParse`. The results are rendered as plain text in an HTML `<pre>` element.

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. It uses d3.csv to fetch the CSS Named Colors data, then reports the file size in kilobytes, the number of rows, and the number of columns. The code includes commented alternatives using fetch, async/await, and d3.csvParse, along with a nested promise example, to illustrate different approaches to handling asynchronous data loading. The final result appears as large text in a pre element.

Loading and Parsing CSV Data

This example demonstrates loading and parsing CSV data from a remote URL, displaying the file size, row count, and column count as large text. Using D3 v5’s `d3.csv` method, it fetches the CSS Named Colors dataset and formats the results with `d3.csvFormat`. An alternative approach using the Fetch API with `async`/`await` and `d3.csvParse` is included in comments, alongside a commented “pyramid of doom” example. The page renders the summary statistics inside a `<pre>` element within a React framework.

The code uses `d3.csv` with a Promise to fetch and parse the data, then formats a summary message with `d3.csvFormat`. An alternative commented-out approach uses `fetch`, `async/await`, and `d3.csvParse`. The result appears as large text in a `<pre>` element.

Loading and Parsing csv Data

This example demonstrates loading and parsing a CSV file with D3 v7, displaying summary statistics about the dataset in large text. It fetches a remote CSV containing CSS named colors using the `d3.csv` method, which returns a promise that resolves to parsed data. The code then computes the formatted CSV size in kilobytes, counts the number of rows and columns, and renders these values to a `<pre>` element. Commented-out alternatives show the same process using `fetch`, `async/await`, and `d3.csvParse`.

Visualizing D3 and React

This example demonstrates how to load and parse CSV data in a D3 and React application. It fetches a dataset of CSS named colors from a remote URL using the `fetch` API with async/await, then parses the raw text with `d3.csvParse`. The visualization displays summary statistics about the dataset—file size in kilobytes, row count, and column count—as large text in a `<pre>` element. The code highlights the contrast between the commented-out `d3.csv` approach and the manual `fetch`-based method.
