This example demonstrates a basic scatter plot for exploring the relationship between sepal length and sepal width in the Iris dataset. The React app includes a file input that lets users load their own CSV data. It uses D3 v7’s `scaleLinear` and `extent` to map data values to SVG coordinates, with points rendered as `circle` elements via a `join` operation. The plot updates dynamically upon file upload.

Basic Scatter Plot with React & D3

This example presents a basic scatter plot that visualizes the Iris dataset, which users load as a CSV file through a file input. The React application parses the data and, using D3's `select` and `join` API, renders circles within an SVG element. The `viz.js` module configures linear scales via `scaleLinear` and `extent` to map sepal length and width values to the plot's dimensions, styling each point with a fixed radius and fill color. The chart updates whenever a new file is selected.

Basic Scatter Plot with React & D3

This example shows the classic Iris flower dataset in a basic scatter plot. It plots sepal length on the x-axis against sepal width on the y-axis, with each of the 150 data points rendered as a small black circle. The code uses React for component state and effects, while D3 v7’s `select`, `scaleLinear`, and `extent` functions handle the SVG element selection and linear scale mapping. The data is loaded from a CSV file using D3’s `csv` method and passed to a reusable `viz` function for rendering, following a clean separation between React and D3 logic.

Basic Scatter Plot with React & D3

This example shows a basic scatter plot of the classic Iris flower dataset, plotting sepal length on the x-axis against sepal width on the y-axis. Each point is rendered as a black circle with a fixed radius of 12 pixels. The visualization is built with React and D3 v7, where React manages the component lifecycle and state, while D3's `scaleLinear` and `extent` functions compute the scales. The `csv` loader reads the data, and the `select` and `join` methods render the circles into an SVG element.

Basic Scatter Plot with React & D3

A basic scatter plot displays the classic Iris flower dataset, plotting sepal length on the x-axis against sepal width on the y-axis for all 150 specimens. Each point appears as a fixed steelblue circle. The React app loads the CSV data via D3's `csv` function, then calls a separate `viz` function that uses `scaleLinear` and `extent` to compute the chart's scales. D3's `select` and a `.join` operation render the circles onto the SVG element.

Scatter Plot with React & D3

This scatter plot visualizes the Iris dataset, showing sepal length against sepal width for 150 flowers. The React `App` component loads CSV data via `csv` from D3 and renders an SVG, while a reusable `viz` function creates the scales, axes, and circles. It uses `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` from D3 v7, with helper modules for axes and labels. The plot displays black circles of radius 12 with labeled x and y axes on a fixed 960x500 canvas.

1Scatter Plot with React & D3

This scatter plot visualizes the Iris dataset, plotting sepal length on the x-axis against sepal width on the y-axis for 150 individual flowers. The visualization is built using `d3.scaleLinear` for axis scaling and `d3.extent` to compute data domains, with React managing the SVG element lifecycle and state. It loads CSV data asynchronously via `d3.csv`, renders axes with `d3.axisBottom` and `d3.axisLeft`, and draws circles for each data point. The chart includes labeled axes and uses a fixed black fill for all points.

scatter plot with react and d3

This scatter plot displays the relationship between sepal length and sepal width from the classic Iris dataset, with each point representing a flower specimen. Built with React and D3 v5, the visualization renders as an SVG using `scaleLinear` for both axes, with `extent` computing the domains from the CSV data loaded via `csv`. The implementation separates axes and marks into reusable components, while a native SVG `<title>` element provides tooltip functionality.

Scatter Plot

This scatter plot displays the relationship between sepal length and sepal width from the Iris dataset. The visualization uses React to render SVG elements, with D3 utilities for data loading, scaling, and axis generation. The code employs `d3.csv` to fetch and parse the Iris data, `d3.scaleLinear` to map values to pixel coordinates, and custom React components for rendering axes and circular marks with hover tooltips. The plot features a clean design with gray tick marks, labeled axes, and teal-colored data points.
