Forked from Loading and Parsing CSV Data

This example demonstrates the initial step of working with the COVID-19 time-series dataset from the CSSE at Johns Hopkins University, showing the file size, row count, and column count of the data. It loads a global deaths CSV via `d3.csv` with a promise, then extracts the latest date column from the data’s headers. The computed metadata is displayed in a large `<pre>` element using plain DOM manipulation. The code uses D3 v5’s `csv` and `csvFormat` APIs, with no additional visualization or rendering beyond text output.

Loading and Parsing Coronavirus Data

This example demonstrates how to load and parse a global coronavirus deaths time-series dataset. It fetches CSV data from the Johns Hopkins CSSE GitHub repository using the `d3.csv` method, which returns a Promise. After loading, the program computes and displays summary statistics—the file size in kilobytes, the number of data rows, and the number of columns—within a large HTML `<pre>` element. The visualization uses D3 v5’s `csvFormat` to calculate the byte length of the formatted data, highlighting a straightforward data-processing workflow without any graphical chart.

Loading and Parsing Coronavirus CSV Data

This example demonstrates loading and parsing the Johns Hopkins Coronavirus global deaths time-series CSV dataset, displaying its size in kilobytes, row count, and column count. It uses d3.csv to fetch and parse the remote CSV file, then calls d3.csvFormat on the resulting data to measure its formatted length. The interface presents these metrics in a large HTML `<pre>` element, with the React framework integrating the D3 v5 code. The code also comments on alternative approaches using fetch, async/await, and nested promises.

Loading and Parsing Coronavirus Data

This example demonstrates the initial step of loading and parsing a global coronavirus death time-series dataset from the Johns Hopkins CSSE GitHub repository. The page prominently displays the raw CSV data in a large, readable font within a `<pre>` element, though the code itself only retrieves the data and identifies the latest date column from the dataset. The visualization uses `d3.csv` to fetch and parse the remote CSV file, with the D3 library version 7 loaded from a CDN. The code explicitly references the final column containing the most recent date's death counts.

Loading and Parsing Coronavirus Data

This example demonstrates loading a global COVID-19 death time-series dataset using D3 v5. It fetches a CSV file from the Johns Hopkins CSSE GitHub repository and parses it with `d3.csv`. The visualization displays a large-text summary showing the data’s size in kilobytes, the number of rows, and the number of columns, computed via `d3.csvFormat` and the parsed array’s properties. It relies on the native `fetch` API and a promise handler, with commented alternatives using `async`/`await` and nested callbacks.

Loading and Parsing Coronavirus Data

This visualization demonstrates how to load and parse the Johns Hopkins Coronavirus Dataset, displaying basic file statistics in a large preformatted text element. It fetches the global deaths time series CSV via `d3.csv`, then computes the data size in kilobytes using `d3.csvFormat`, and counts the rows and columns from the parsed array and its `data.columns` property. The final message shows the latest date column, total file size, row count, and column count, all rendered into the DOM via `textContent`. The example highlights D3’s Promise-based data loading and inspection of CSV metadata.

Loading and Parsing Coronavirus Data

This example demonstrates the raw size and structure of the Johns Hopkins Coronavirus Dataset by displaying three key metrics: file size in kilobytes, row count, and column count. It loads the global deaths time-series CSV and parses it using `d3.csv`, then reports the number of columns from the dataset’s header. The code computes the file size from `d3.csvFormat(data).length` and renders the results as large text in a `<pre>` element via `textContent`. It uses D3 v5’s promise-based loading API.

Loading and Parsing Coronavirus Data

This example loads the Johns Hopkins Coronavirus global deaths time-series dataset and displays basic file statistics: the approximate size in kilobytes, the number of rows, and the number of columns. It retrieves the CSV from a GitHub raw URL using `d3.csv` and the Promise-based `.then` method, then formats the data with `d3.csvFormat` to compute its length. The resulting message is rendered into a large `<pre>` element using standard DOM selection. The code demonstrates parsing and summarizing a tabular dataset with D3 v5.

Loading and Parsing Coronavirus Data

This example displays the size and structure of the Johns Hopkins Coronavirus time-series dataset as large text. It uses D3 v5’s `d3.csv` to load the global COVID-19 deaths CSV and `d3.csvFormat` to measure the file size in kilobytes. The code then counts the number of rows and columns and updates the page’s `<pre>` element with these three statistics.
