This visualization displays a scatter plot of automotive data from the UCI Auto MPG data set, mapping fuel efficiency (mpg) against horsepower. Each circular mark is colored by country of origin and sized by vehicle weight, with tooltips revealing car model names. The chart demonstrates the Vega-Lite API (vl) for D3, where the programmatic specification defines encoding channels like `vl.x().fieldQ('mpg')` and `vl.color().fieldN('origin')`. The code registers Vega, Vega-Lite, and the Vega-Lite API, then reads CSV data via `d3.csv` to render interactive SVG output.

AI-generated description

A visualization constructed using the vega-lite-api.

The data shown here comes from the UCI Machine Learning Repository: Auto MPG Data Set, via Gist: Scatter Plot with Menus.

This interactive scatter plot explores the relationship between fuel efficiency (mpg) and horsepower across vehicles from different origins, with point size encoding weight and color indicating country of origin. Built using the Vega-Lite API on top of D3, the visualization leverages `vl.markCircle`, `vl.x().fieldQ()`, `vl.y().fieldQ()`, `vl.color().fieldN()`, and `vl.size().fieldQ()` to map the Auto MPG dataset from the UCI Machine Learning Repository. The code registers Vega-Lite specifications, applies a custom dark-themed configuration for readability, and renders to an SVG canvas with tooltips for inspecting data points.

This example displays a scatter plot of the Auto MPG dataset from the UCI Machine Learning Repository, showing vehicle fuel efficiency against horsepower. Each circle’s size encodes vehicle weight and its color represents the country of origin, with tooltips revealing the car model name. The visualization is built using the Vega-Lite API, which compiles specifications into Vega and renders with D3. Data is fetched as CSV via D3’s `csv` function, and styling customizes axis labels and titles for readability.

This visualization displays a scatter plot of automotive data from the UCI Auto MPG dataset, mapping engine horsepower against fuel efficiency (mpg). Each point’s color encodes the car’s country of origin, while the point size represents vehicle weight and a tooltip reveals the car model name. The code uses the Vega-Lite API to declaratively build the chart, with D3’s `csv` function for data loading and Vega tooltip for interactive hover details. The visualization dynamically fits to the browser window dimensions.

This scatter plot visualizes automotive fuel efficiency and performance data from the UCI Auto MPG dataset, showing the relationship between miles per gallon and horsepower while encoding vehicle origin via color and weight via marker size. The visualization is built programmatically using the Vega-Lite API, which constructs a declarative specification that is then rendered through Vega and Vega-Lite JavaScript libraries. Data is loaded asynchronously from a GitHub Gist using the `csv` function from d3.v5, while the Vega Tooltip handler provides interactive hover details displaying each car model's name. The chart auto-fits to the browser window dimensions.

This visualization displays automobile data from the UCI Machine Learning Repository’s Auto MPG dataset as a scatter plot, showing miles per gallon against horsepower, with color encoding the country of origin and point size representing vehicle weight. The plot uses a dark-themed, large-label aesthetic for clarity. It is built with the Vega-Lite API, which is registered with Vega and Vega-Lite, and uses D3’s `csv` loader to fetch the data. The interactive tooltip is provided by Vega Tooltip, and the chart renders as SVG, fitting the full browser window.

This example presents an interactive scatter plot of the Auto MPG dataset from the UCI Machine Learning Repository, visualizing relationships between fuel efficiency, horsepower, vehicle weight, and country of origin. Each circle’s position maps to miles per gallon and horsepower, while size encodes weight and color distinguishes origin, with tooltips revealing car names. Built with the Vega-Lite API, it registers Vega, Vega-Lite, and Vega-Tooltip through D3’s CSV loader for data retrieval, then renders a fit-sized SVG view with custom styling for readability.

This visualization presents a scatter plot of the Auto MPG dataset from the UCI Machine Learning Repository, showing the relationship between miles per gallon and horsepower for various car models. Each point’s size encodes vehicle weight, color indicates the country of origin, and hovering reveals the car name. Built with the Vega-Lite API, it registers Vega, Vega-Lite, and d3, using `vl.markCircle` for encoding and `d3.csv` for loading data. The plot spans the full browser window with a custom dark color config for axis labels and titles.

This interactive scatter plot visualizes the relationship between fuel efficiency (mpg), horsepower, and weight for various car models, with the country of origin represented by color. Built using the Vega-Lite API, it loads data from the UCI Auto MPG dataset and renders circles with a fixed size and opacity. The visualization leverages `vl.markCircle` and `vl.encode` for encoding, while `window.innerWidth` and `window.innerHeight` determine the canvas size. The code uses `d3.csv` for data ingestion and a custom `config` for axis styling, with tooltips handled via vega-tooltip. The visualization is generated dynamically and appended to the document body.
