This scatterplot of the Iris dataset uses geometric symbols to encode the flower species, with sepal length and width mapped to the x and y axes. The size of each symbol additionally encodes petal length. Rendered using D3.js v4 with SVG, the visualization employs `d3.scaleOrdinal` to assign both colors from the `d3.schemeCategory20` palette and distinct symbol types via `d3.symbols`. An interactive legend allows users to isolate a single species by clicking its label, which filters the displayed marks by toggling their opacity.

Scatterplot Iris using different marks

This example visualizes the classic Iris dataset as a scatterplot, mapping sepal length and width to the x- and y-axes. Each data point is rendered as a distinct SVG symbol—circle, cross, or diamond—based on the flower’s species, with color further distinguishing the three classes. The code uses d3.scaleLinear for axes, d3.scaleOrdinal for color and symbol assignment, and d3.symbol with the d3.symbols array to generate the mark paths. A legend maps species to both symbol type and color, while petal length is encoded by a square-root size scale.

Interactive Scatterplot Iris using different marks

This interactive scatterplot visualizes the classic Iris dataset, using four quantitative variables to position and size each flower sample. The x and y axes map sepal length and width, while petal length controls the size of each point through a square-root scale. Each of the three Iris species is encoded with a unique symbol and color, assigned via d3.symbols and d3.scaleOrdinal. Clicking a legend item filters the plot by dimming non-selected species, offering a simple way to compare groups. The visualization is built with D3.js v4, rendering marks as SVG paths within an HTML page.

[interactive] Scatterplot Iris using different marks

This interactive scatterplot displays the classic Iris dataset, plotting sepal length against sepal width. Each flower is represented by a distinct SVG symbol whose shape and color encode its species. The visualization uses d3.scaleOrdinal with d3.symbols to generate different mark types, while d3.scaleLinear maps the quantitative axes. A legend allows filtering by clicking on a species, which dims all other symbols by reducing their opacity. The code relies on d3.csv for data loading and d3.axisBottom and d3.axisLeft for the axes.

scatter plots with different symbols

This scatter plot displays the Iris dataset, mapping petal width on the x-axis and sepal length on the y-axis. Three species markers use different D3 symbol shapes, generated with `d3.symbol` and `d3.symbols`. A `d3.scaleOrdinal` assigns symbols, while `d3.scaleLinear` handles axes, rendered with `d3.axisLeft` and `d3.axisBottom` in an SVG. The chart is built with a reusable `scatterPlot` function using D3 v6.

Scatter Plot

This scatter plot visualizes the Iris dataset, mapping petal width on the x-axis against sepal length on the y-axis. It uses distinct symbols for each iris species, generated via D3's `scaleOrdinal` and `symbol` APIs to differentiate categories. The plot is rendered as an SVG, with axes created using `axisLeft` and `axisBottom`. The reusable chart component, inspired by Bostock’s "Towards Reusable Charts," accepts configurable data, value accessors, margins, and symbol size, demonstrating a modular approach to D3 visualization.

Reusable scatter plot with different symbols

This example visualizes the Iris Dataset, mapping petal width to the x-axis and sepal length to the y-axis. Each data point is rendered as a distinct symbol from D3’s `symbols` set, with the species of iris determining which symbol shape is used. The visualization is built as a reusable D3 component using `scaleLinear`, `scaleOrdinal`, `axisLeft`, `axisBottom`, and `symbol().size(100)` to generate the scatter plot’s marks. The `scatterPlot` function is configured with margin, size, and accessor functions, while the SVG rendering fills the browser viewport.

Scatterplot Iris (d3.v4)

This scatterplot visualizes the classic Iris dataset using D3.js v4, mapping sepal length and width to the x- and y-axes. Each flower is represented by a circle whose radius encodes petal length, while color distinguishes species (setosa, versicolor, virginica) via a categorical scale. The chart includes labeled axes, a legend, and hover tooltips that display the species of each point. Built with SVG and animation, the visualization offers an interactive overview of the dataset’s structure and species groupings.

Scatter Plot with Symbols

This scatter plot displays the Iris Dataset, mapping petal width and sepal length on the x- and y-axes. Each data point is rendered as a distinct SVG symbol according to the flower species, using the d3 symbols API with a size of 100. The implementation builds a reusable scatter plot module with d3.scaleLinear, d3.scaleOrdinal, d3.axisLeft, and d3.axisBottom. Data is loaded from a CSV file via d3.csv, and the plot fills the browser window by setting width and height to window dimensions.
