This example combines an area chart and a line chart on a shared y-axis, rendering 20 randomly generated data points as a smooth basis curve. The SVG output uses two D3 v4 modules: `viz.area()` fills the area beneath the curve with semi-transparent green, while `viz.line()` draws the line itself in solid green. A left-oriented axis with grey ticks and horizontal gridlines is created using `d3.axisLeft()`. The data is generated on the fly by `randomData()`, and the chart is assembled by passing the area and line components to a single `d3.select("g")` selection.

Viz - Area - line

This example combines a filled area chart with an overlaid line chart to visualize 20 random data points generated by `randomData()` via `d3.range` and `Math.random`. The area uses a red fill with low opacity, while the line is drawn in solid red, both smoothed with `d3.curveBasis`. The code relies on the `viz.area()` and `viz.line()` APIs from the Viz.js library, which internally leverage D3 v4 scales and shapes, and renders to an SVG element selected from the page.

Viz - Area - Line - Point

This example combines three chart types—an area, a line, and points—to visualize a dataset of twenty random values. The area uses a cardinal curve to create a smooth, filled shape, while the line traces the same values with a distinct stroke, and points mark each data location. Built with D3 v4 and the vizjs library, it renders to SVG, with the point layer using a custom `drawPoints` function to append circles. The data is generated on the fly via `randomData()`, and all three layers are drawn onto a shared group element.

Viz - Area - curve

This example draws a smooth area chart from twenty randomly generated data points. It uses the Viz.js library’s `area` generator, configured with a basis curve via `d3.curveBasis`, and renders the result as an SVG path with a steelblue fill. The random data is created on the fly using `d3.range`, and the chart is placed inside a `<g>` element translated within an SVG canvas.

Viz - Area - Default

This example demonstrates a basic area chart generated from twenty random data points, where each point consists of a key and a value. The chart fills the area beneath the line with a steelblue color. The visualization is rendered as an SVG element, with the chart drawn inside a group that is translated 50 pixels from the top-left corner. The code uses the `viz.area()` function from the Viz.js library, invoked via `d3.select("g").call(...)`, and generates its random input data using `d3.range` and `Math.random`.

Viz - Line - Axis

This example shows a simple line chart built with D3.v4 and Viz.js, plotting ten random data points connected by a steelblue path. The code explicitly constructs an x-axis using `d3.axisBottom()` scaled to the line’s key scale, and a y-axis via `d3.axisLeft()` on the value scale, with both axes and the line appended to an SVG group. Each data point is rendered as a white circle with a red stroke, and the underlying data is generated on the fly using `d3.range(10).map(...)` to produce key-value pairs. The visualization is rendered as SVG with a 960×500 viewport.

Viz - Area - orient left

This example demonstrates a left-oriented area chart, with a smooth curve flowing horizontally from the left edge of the SVG canvas. The visualization renders 20 randomly generated data points, where each point’s value falls between 0 and 1, mapped as a single filled steelblue region. The chart is built using the Viz.js library’s `viz.area()` method, configured with `orient("left")` and a basis curve from `d3.curveBasis`, then appended to an SVG group via D3’s selection and call pattern. The SVG output is fixed at 960 by 600 pixels, with the chart translated 50 pixels from both axes.

Viz - Area - ease

This example demonstrates an animated area chart built with D3.js and the viz.js extension. Twenty random data points, each with two values, form a smooth, stacked area that updates every two seconds. The chart uses `d3.curveBasis` for its curved path and applies a bounce-out easing effect via `d3.easeBounceOut` during transitions. The visualization is rendered as an SVG and leverages the viz.js `area()` function to manage the data, value scales, and transition updates.

Viz - Line - axis ticks

This visualization displays a simple line chart of ten random data points, with each point rendered as a red-bordered circle connected by a steelblue stroke. The example demonstrates how to add axis ticks and a grid using D3 v4’s `d3.axisLeft` with a custom `tickSize` that extends the ticks across the plot width. The chart is built using the `viz` library (v1.3.0) to generate the line and value scale, while SVG elements are styled via CSS classes for the grid lines, domain, and circles. Data is produced on the fly with `d3.range` and `Math.random`.
