This example pairs a heatmap with Vega-Lite’s declarative API to visualize daily temperature readings. The chart plots date fields on both axes, using semi-transparent pink points to reveal density patterns, with tooltips showing the raw Temperature value. The visualization is built with `vega-lite-api`, registered alongside `vega` and `vega-lite`, and loads CSV data via d3’s `csv` function. Custom config adjusts axis labels and tick colors for readability, while the canvas is sized to fit the full viewport.

Vega-Lite API Template

This example uses the Vega-Lite API to render a temperature time series as a line chart over the full viewport. The visualization displays temperature readings across timestamps, with tooltips showing individual values on hover. The code loads CSV data from an external URL via the `d3.csv` method, then constructs the chart using `vl.markLine` and `vl.encode` functions from the `vega-lite-api` library. Appearance is customized through a configuration object that adjusts axis labels and title styles.

Vega-Lite API Temp Template

This example visualizes temperature trends over time using a filled area chart. The visualization is built with the vega-lite-api library, which wraps the Vega-Lite grammar for programmatic chart specification, and renders through Vega with SVG output. Data is loaded asynchronously from a CSV file using d3.csv, showing temperature values on the y-axis and timestamps on the x-axis. The chart includes tooltips for individual data points, custom axis styling from a configuration object, and adapts to fit the browser window dimensions.

Vega-lite - template

This example uses Vega-Lite to render an area chart with yearly time on the x-axis and a non-zero-based quantitative total on the y-axis, with tooltips showing temperature values. The visualization is built programmatically using the `vega-lite-api` library, which registers Vega and Vega-Lite to produce an SVG. Data is loaded asynchronously from a remote CSV file using `d3.csv`. The chart fills the window and applies custom axis and label styling from a config object, with tooltips provided by the `vega-tooltip` Handler.

Vega-Lite API Template

This visualization displays temperature data as a shaded area chart, with temperature on the y-axis and timestamp on the x-axis. The example demonstrates the Vega-Lite API, where the visualization specification is built programmatically using `vl.markArea()`, `vl.x().fieldT()`, and `vl.y().fieldQ()` methods, rather than a static JSON spec. It registers Vega and Vega-Lite libraries, uses a custom dark-themed configuration for axes and labels, and loads CSV data from a remote URL via `d3.csv`.

Vega-Lite API Template - linechart

This line chart visualizes daily temperature trends using the Vega-Lite API, which programmatically defines a line mark with encoded temporal x-values and quantitative y-values. Data is loaded asynchronously via D3’s `csv` parser from a San Francisco temperature dataset. The example demonstrates a minimal Vega-Lite specification, with tooltips enabled through vega-tooltip and custom axis styling in a separate config file. It integrates Vega, Vega-Lite, and the Vega-Lite API libraries, rendering to SVG and fitting the full browser window.

Vega-Lite API Template

This example shows a line chart of temperature readings over time, rendered as a single thick stroke. The visualization uses the Vega-Lite API to specify the mark type and encodings, including the x-axis as a temporal field and the y-axis as a quantitative field with a non-zero scale. Data is fetched from a CSV file containing weekly San Francisco temperature measurements using d3’s `csv` function. The code registers Vega-Lite and Vega-Tooltip to enable interactive tooltips, and applies custom axis styling from a configuration object.

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 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.
