This example shows the Iris dataset transformed into a summary of average sepal length per species, displayed as formatted JSON text in a `<pre>` element. The visualization fetches and parses `data.csv` using `d3.csvParse`, then applies `d3.flatRollup` and `d3.sum` to compute the species averages. The code also demonstrates a state management pattern with `setState` for handling loading states, rendering the result with D3’s `select` and `join` methods.

Transforming Data

This example demonstrates data transformation using the Iris dataset. It loads a CSV file and computes the average sepal length for each species, displaying the resulting summary as JSON text in a `<pre>` element. The visualization uses D3 v7 APIs including `csvParse` for data loading, `flatRollup` for grouping and aggregation, and `sum` for calculating totals. The implementation follows a state-based pattern with a `setState` function to manage the asynchronous data fetching and rendering lifecycle.

Transforming Data

This example demonstrates how to load, transform, and summarize the classic Iris dataset. It fetches a CSV file, parses it with `d3.csvParse`, converts numeric fields, and then uses `d3.flatRollup` and `d3.sum` to compute the average sepal length for each species. The resulting summary is displayed as a JSON string in a `<pre>` element. The code relies on D3 v7 for data parsing and aggregation, and uses a simple state-management pattern with `setState` to handle asynchronous loading.

Transforming data

This example demonstrates data transformation by loading the classic Iris dataset from a CSV file and computing the average sepal length for each species. It uses D3 v7 modules such as `csvParse`, `flatRollup`, and `sum` to parse the data, aggregate it by species, and display the resulting summary as JSON in a `<pre>` element. The visualization also shows asynchronous state management with `setState` and a loading indicator.

Transforming Data

This example demonstrates data transformation with the Iris flower dataset, computing the average sepal length for each species and displaying the result as formatted JSON text. The visualization begins by fetching data.csv and parsing it with `d3.csvParse`, converting numeric fields from strings to numbers. It then uses `d3.flatRollup` combined with `d3.sum` to group records by species and calculate mean sepal lengths, with the final output rendered as a `<pre>` element via D3's `select` and `join` methods.

Transforming Data

This example loads the classic Iris dataset from a CSV file and computes the average sepal length for each species. The visualization displays this calculated result as formatted JSON text in a `<pre>` element, demonstrating a simple data-transformation pipeline from raw tabular data to a summary table. The code uses D3 v7 functions including `csvParse` for data loading, `flatRollup` and `sum` for aggregation, and `select` for DOM updates. It also showcases ES6 module imports and a state-management pattern for asynchronous data fetching.

Transforming Data

This example demonstrates how to transform the classic Iris dataset by computing the average sepal length for each species using `d3.flatRollup` and `d3.sum`, then displaying the aggregated results as a JSON summary in a `<pre>` element. The visualization loads CSV data asynchronously via `fetch`, parses it with `d3.csvParse`, and converts numeric fields before processing. Built with D3 v7 and ES6 modules, it showcases lazy state management where data is fetched and transformed only once on initial render.

Transforming Data

This example demonstrates data transformation by loading the classic Iris dataset from a CSV file and computing the average sepal length for each species. It uses D3's `csvParse` to parse the data, `flatRollup` and `sum` to aggregate values, then displays the resulting summary as JSON text in a `<pre>` element. The visualization highlights D3 v7’s modular import system and local ES6 modules, with a simple state management pattern that asynchronously fetches and processes the data before rendering.
