This example demonstrates rapid iteration with the Vega-Lite API by rendering an area chart of San Francisco weekly temperatures. The visualization maps temperature values over time, displaying the data as a smooth, filled area graph. The code leverages the `vega-lite-api` to build the specification, with `vl.markArea()` and `vl.x().fieldT()`/`vl.y().fieldQ()` encoding the temporal and quantitative fields. It uses `vega` and `vega-lite` for rendering, `vega-tooltip` for interactivity, and `d3.csv` to load the dataset from the UCI Machine Learning Repository Auto MPG data source.

Vega-Lite API Template

This example uses Vega-Lite API to render an interactive area chart of weekly temperature data for San Francisco. The visualization shows temperature readings over time, with tooltips displaying the temperature value on hover. The code imports data from a CSV file using d3.csv and then passes it to a Vega-Lite specification that defines the x-axis as timestamps and the y-axis as quantitative temperature values. The chart is configured with custom axis styling and uses vega, vega-lite, and vega-tooltip libraries to handle rendering and interactive tooltips.

Vega-Lite API Temperature Area Chart

This example visualizes weekly temperature data for San Francisco as a smooth area chart, with the y-axis mapping temperature values and the x-axis representing timestamps. It demonstrates the Vega-Lite API by programmatically constructing a chart specification using its method chaining, including `vl.markArea`, `vl.x().fieldT`, and `vl.y().fieldQ`. The visualization is rendered via Vega and Vega-Lite, with data loaded using d3.csv, and uses custom axis styling from a shared config plus a tooltip handler from Vega Tooltip.

11.-Vega-Lite API 2

This example visualizes San Francisco weekly temperature data as a single smooth area chart, with time on the x-axis and temperature on the y-axis. Built using the Vega-Lite API 2, the chart leverages `vl.markArea`, `vl.x().fieldT`, and `vl.y().fieldQ` to encode temporal and quantitative fields. It pulls data via `d3.csv` from a gist URL, registers Vega and Vega-Lite, and renders interactively with a tooltip handler, while custom axis and label styling improve readability.

Vega-Lite API Template

This example demonstrates a temperature-over-time visualization using an area mark. It plots weekly temperature readings for San Francisco, with time on the x-axis and temperature on the y-axis. The code builds the chart declaratively using the Vega-Lite API, registering it with Vega and Vega-Lite, and loads the dataset via d3.csv. The chart renders as an SVG, includes tooltips via Vega Tooltip, and applies custom axis and label styling from a shared config.

Vega-Lite API Template - Line/Area chart

This example shows a line-area chart of weekly temperature data for San Francisco, with the area fill emphasizing the variation in temperature over time. The visualization is built using the Vega-Lite API, with `vl.markArea()` defining the mark type and `.encode()` mapping the `timestamp` field to the x-axis and `temperature` to the y-axis. Data is loaded asynchronously via `d3.csv` from a GitHub Gist, and the chart is rendered with an SVG view, configured with custom axis styles and tooltips through the `vega-tooltip` handler.

Vega Lite API

This example visualizes temperature fluctuations over time using a Vega-Lite area chart, with data sourced from a CSV of weekly San Francisco temperatures. The visualization loads data via D3’s `csv` method and constructs the chart programmatically using the `vega-lite-api` library, registering it with Vega and Vega-Lite. The chart encodes time on the x-axis and quantitative temperature values on the y-axis, with a tooltip displaying the temperature. Custom styling through a `config` object adjusts axis labels, titles, and colors, while the rendering is handled as an SVG via Vega’s view renderer.

Vega-Lite API Line Chart

This example renders a line chart of San Francisco weekly temperatures using the Vega-Lite API within a D3.js framework. The visualization displays temperature trends over time, with tooltips showing exact temperature values on hover. The code uses `vl.markArea` with encoded x- and y-fields, pulling data from a CSV via D3's `csv` loader. It integrates Vega, Vega-Lite, and the Vega-Lite API for declarative visualization, while customizing axis and label styling through a separate config file.

Vega-Lite API Template

This interactive visualization uses the Vega-Lite API to render a scatter plot of weekly temperature readings from San Francisco. The visualization maps timestamp to the x-axis and temperature to the y-axis, with color encoding timestamps and tooltips showing temperature values. Built with d3.csv for data loading, it employs vega-lite-api’s vl object to construct circle marks with configurable styling, drawing directly to an SVG canvas sized to the window. The underlying data originates from the UCI Machine Learning Repository’s Auto MPG dataset.
