This example demonstrates data transformation by fetching a CSV file of stock data, parsing it with `d3.csvParse`, and grouping the records by industry using `d3.flatGroup`. It then counts the number of stocks per industry and displays the resulting summary as a JSON string in a `<pre>` element. The visualization uses D3 v7's selection and join APIs to render the computed counts, showing a simple text-based aggregation of the underlying dataset.

Transforming Data

This example transforms a CSV file of S&P 500 stock data for 2022 into a summary of stock counts per industry. It demonstrates data-processing pipelines from the D3 library, including `flatGroup` to aggregate records by industry, `csvParse` to load the data, and `select` to render the resulting count as formatted JSON text. The visualization initially fetches the data from a remote gist URL, parses numeric fields, and then updates its display using a state-based rendering loop.

Transforming Data

This visualization demonstrates data transformation techniques, specifically binned aggregation, using the D3.js library. It loads S&P 500 stock data from a CSV file and applies various D3 operations such as `flatGroup` and `flatRollup` to summarize the data. The example groups the dataset by industry and displays the resulting summary as a JSON object on the page. The code also includes commented-out examples of other transformations, such as computing minimum, maximum, extent, and creating binned histograms. The final output shows the transformed data structure in a simple text format.

Fork of Transforming Data

This visualization uses NHL playoff data to display the number of seasons each team has made the playoffs. The code transforms the dataset with d3.flatGroup, grouping records by team and counting occurrences, then outputs the resulting summary as JSON in a pre element. The example demonstrates D3 v7 data loading with csvParse and data transformation workflows.

Fork of Loading and Parsing CSV Data

This visualization demonstrates how to load and parse CSV data using D3.js version 5. It fetches an electric accounts dataset from a GitHub-hosted CSV file and displays basic statistics about the data, including file size in kilobytes, row count, and column count. The implementation uses `d3.csv` to asynchronously retrieve and parse the data, then formats the information with `d3.csvFormat`. The result appears as large text in an HTML `<pre>` element, showing how fetched tabular data can be summarized and presented.

Fork of loading and parsing csv data

This example demonstrates how to load and summarize a CSV dataset of furniture inventory using D3.js and React. It displays a data summary, including file size in kilobytes and bytes, row count, and column count, in a `<pre>` element. The code uses `d3.csv` to fetch and parse the data from a remote URL, then `d3.csvFormat` to calculate the byte size. The page also includes an SVG icon and an image, with styling handled by external CSS. The visualization highlights basic data inspection techniques rather than complex graphical encodings.

Transforming Data

This example demonstrates data transformation from a CSV file using D3.js. The visualization loads fruit pricing data and calculates the average sepal length for each species using `flatRollup` and `sum`. The transformed data is then rendered as a JSON string in a `<pre>` element. The code utilizes `csvParse` for data ingestion, `select` for DOM manipulation, and the `flatRollup` aggregation API to summarize the dataset.

Fork of ICE-5: Loading and Parsing CSV Data with D3.js

This example demonstrates how to load and parse CSV data from a remote URL using D3.js v7. The page displays a summary of the dataset, including its size in kilobytes, row count, and column count, within a styled `<pre>` element. The code uses `d3.csv` to fetch and parse the data, then `d3.csvFormat` to calculate the data size, and writes the results to the DOM via `document.getElementById`. The visualization also embeds a static SVG image as a decorative element.

Fork of Fork of ICE-5:fork Loading and Parsing CSV Data with D3.js

This visualization demonstrates how to load and parse a CSV dataset using D3.js v7, displaying the file size, row count, and column count in a styled HTML header. The code calls `d3.csv()` on a remote CSV file from a GitHub gist containing state-level data, then formats the response with `d3.csvFormat()` to calculate the data size. The result is rendered as text within a `<pre>` element, alongside an embedded SVG illustration, and the page uses inline CSS for visual styling.
