Carregando dados com React e D3

Loading data with d3 and react

This example demonstrates how to load a CSV dataset and display its summary statistics as oversized text in a React application. The app fetches data from a GitHub Gist URL using the `d3.csv` method, then formats a message with file size in kilobytes, row count, and column count using `d3.csvFormat` and the data’s metadata. Rendered inside a `<pre>` element, the result updates from “loading…” to the computed statistics once the data arrives. The code uses React hooks (`useState`, `useEffect`) and the `ReactDOM.render` API with D3 v7.

Load the data React + D3

This example demonstrates how to load a CSV file asynchronously in a React application and display summary statistics about the dataset. The interface shows a large text block reporting the file size in kilobytes, the number of rows, and the number of columns. The code uses React hooks (`useState`, `useEffect`, `useCallback`) to manage state and fetch the data, while `d3.csv` loads the remote CSV from a GitHub gist. `d3.csvFormat` calculates the data size, and the ReactDOM renderer updates the display once loading completes.

Loading Data with React & D3

This example demonstrates how to combine React and D3 to load and summarize a CSV dataset, displaying file size, row count, and column count. The app uses React’s `useState` and `useEffect` hooks to fetch data asynchronously via `d3.csv` from a GitHub Gist, then renders the summary using a custom `message` function that leverages `csvFormat`. While loading, it shows a "Loading..." placeholder. The code relies on D3 v7 and React 16.9, with the browser rendering the output in a large `<pre>` element.

data da react

This example demonstrates a minimal React application that loads a CSV dataset and displays summary statistics about it, such as file size, row count, and column count. The visualization is rendered as plain text within a React component, using the `useState` hook to manage the loaded data and `d3.csv` to fetch and parse the remote CSV file from a GitHub gist. The interface shows a loading message before the data arrives, then updates to present the calculated metrics derived from the parsed dataset.

Loading data with React and D3

This example demonstrates loading a remote CSV dataset with React and D3, displaying the file size, row count, and column count as text. The `useState` and `useEffect` hooks manage asynchronous data loading, while D3’s `csv` fetches the CSS named colors data from a GitHub gist. The message is generated with `d3.csvFormat` to calculate byte size, and rendered as large text in an SVG-free `<pre>` element. React 16.9 and D3 v5 handle the data pipeline and rendering.

Loading Data with React & D3

This example demonstrates how to load external CSV data into a React application using D3’s `csv` method, then display a summary of the dataset’s size and structure. The React `useEffect` hook fetches the CSV from a GitHub gist, storing the parsed data in state via `useState`. Once loaded, the `message` function formats the output using `d3.csvFormat` to calculate file size in kilobytes, alongside row and column counts. The interface shows the text summary inside an HTML `<pre>` element, with a simple “loading” placeholder before data arrives.

Loading Data with React & D3

This example shows how React state and D3 utilities work together to load and summarize a CSV dataset. It displays the file size in kilobytes, the number of rows, and the number of columns inside a large <pre> element. The code uses React’s `useState` and `useEffect` hooks to fetch the CSV from a GitHub gist via `d3.csv`, then formats the result with `d3.csvFormat` and passes it to a custom message function. The visualization is minimal, focusing on data-loading mechanics rather than graphical output.

Loading data with React and D3

This example demonstrates how to load and display a CSV dataset in a React application, showing a text summary of the data size, row count, and column count once the file is fetched. The code uses React’s `useState` and `useEffect` hooks to manage the asynchronous loading state, while D3’s `d3.csv` fetches the data from a GitHub gist URL and `d3.csvFormat` converts it back to a string to calculate its size in kilobytes. The visualization initially displays “Loading…” and updates to the summary once the data arrives.
