Forked from Loading and Parsing CSV Data

This example shows the size and structure of a CSV file by displaying the number of kilobytes, rows, and columns in a large text element. It loads CSS named colors data from a remote GitHub gist using d3.csv, which returns a promise. The code then formats the parsed data back into a CSV string with d3.csvFormat to measure its byte length, and accesses the parsed array’s length and columns property for row and column counts. It highlights the less verbose promise-based approach over the commented-out fetch and async/await alternative with d3.csvParse.

Loading and Parsing CSV data

This example demonstrates the basic workflow of loading and parsing a CSV file with D3.js, displaying the data’s size, row count, and column count in a large text element. It uses `d3.csv` to fetch a remote CSV of CSS named colors from a GitHub gist, then computes the formatted string’s kilobyte size with `d3.csvFormat` and `Math.round`. The page also includes commented-out alternatives using `d3.csvParse` with `fetch` and async/await, though only the primary `d3.csv` promise-based method runs.

Loading and Parsing CSV Data

This example demonstrates the loading and parsing of CSV data using D3 v6, displaying the file size, row count, and column count in a large text element. The code fetches a CSV file from a GitHub gist containing named CSS colors and processes it with `d3.csv()`, which returns a promise. The results are formatted using `d3.csvFormat()` to calculate the data’s kilobyte size, while `data.length` and `data.columns.length` report the row and column totals. A commented section also shows an alternative approach using the Fetch API and `d3.csvParse()`.

Loading and Parsing CSV Data

This example demonstrates loading and parsing CSV data with D3.js v6, displaying file size, row count, and column count in a preformatted text block. It fetches a remote CSV file containing CSS named colors from a GitHub gist using `d3.csv`, which returns a promise, then formats the data with `d3.csvFormat` to calculate its kilobyte size. The code also includes commented alternatives using `fetch`, `async/await`, and `d3.csvParse` for manual text-based parsing. The visualization is minimal, focusing on data ingestion metrics rather than graphical output.

Loading and Parsing CSV Data

This example demonstrates how to load and parse a CSV file using D3 v5, displaying the file size, row count, and column count in large text. It uses `d3.csv` to fetch and parse the dataset asynchronously via a promise, then formats a summary message with `d3.csvFormat` to calculate kilobyte size. The data source is a GitHub-hosted CSV containing CSS named colors. An alternate approach using the Fetch API with `async` and `await`, plus `d3.csvParse`, is included as commented-out code for comparison.

Loading and parsing CSV data

This example demonstrates how to load and parse a remote CSV file using D3.js. It renders a summary of the parsed dataset as large text, showing the file size in kilobytes, the number of rows, and the number of columns. The code uses `d3.csv()` with a promise to fetch the CSS named colors dataset from a GitHub gist, then applies `d3.csvFormat()` to measure the data size and accesses `data.length` and `data.columns` for the row and column counts. The result is displayed in a `<pre>` element via `document.getElementById()`.

The code fetches a CSV of CSS named colors from a GitHub gist via `d3.csv`, which returns a promise, and then uses `d3.csvFormat` to measure the data size in kilobytes. The parsed data array and its `.columns` property provide the row and column totals, which are written into the page using standard DOM manipulation.

Loading and Parsing CSV Data

This example demonstrates the basics of loading and parsing CSV data with D3.js. It fetches a remote CSV file containing CSS named colors and displays three summary statistics in a large-text format: the file size in kilobytes, the number of data rows, and the number of columns. Using `d3.csv` with a promise chain, the code accesses the parsed data object and calls `d3.csvFormat` to measure the raw string length. The interface is a simple `<pre>` element updated via `textContent`, with commented alternatives using `fetch` and `d3.csvParse` for comparison.
