This example demonstrates a dual-mode chart that switches between a multi-line comparison and a difference area view, with a toggle control. The multi-line mode overlays two series as linear curves, while the difference mode fills the area between them, coloring increases and decreases distinctly. Hovering triggers a Voronoi overlay to identify the nearest data point and display its y-value. Built with D3 v4, the chart uses SVG for rendering, `d3.area` for the difference path, `d3.scalePoint` for the toggle, and animated transitions via `transition.attrTween` to smoothly update axes and shapes.

AI-generated description

This two series chart toggles between a multi-line chart and a difference area chart. When mouseing over the chart, the closest data point will display it's y-axis measurement.

Area Chart

This example demonstrates an interactive area chart built with D3.js (v4) that presents two overlaid series with gradient fills, rendered as SVG. The visualization initially displays one dataset, and a button click transitions the chart to a second, extended dataset. The chart's axes and area paths smoothly animate their transitions over two seconds using D3's `.transition()` method. The code defines linear gradients with specified opacity stops for series styling, and uses `d3.scaleLinear` and `d3.axisBottom`/`d3.axisRight` for scaling and axes, respectively.

D3 Area - Multiarea

This example shows a multi-area chart built with D3 v7, displaying a gray band between upper and lower y-values across six x-axis points. The chart uses a linear scale to map input values (0–100) to pixel coordinates, while a d3.area() generator computes the path for the filled region. The data is provided as an inline array of objects with x, y0, and y1 fields, and the result is rendered as a single SVG path element inside a 700×400 viewport.

Multi-Line Chart

A multi-line chart displays multiple frequency-domain signals stacked vertically, each with its own amplitude trace and label. The visualization uses D3 v4 to render the data as animated SVG paths, with a skewed perspective and brush-based zooming for interactive exploration. It leverages `d3.scaleLinear`, `d3.axisBottom`, `d3.brushX`, and `d3.line` to handle scaling, axes, brushing, and path generation, while the data comes from a JSON array containing signal measurements.

Multi area chart

This multi-area chart displays two distinct time-series metrics—stock values and their price-to-earnings ratios—across a decade of yearly intervals. The visualization uses a dual-axis layout with an orange-filled area for value data and a purple-filled area for peRatio data, each overlaid with corresponding line strokes. Built with D3 v4, the chart leverages `d3.scaleTime`, `d3.scaleLinear`, `d3.area`, and `d3.line` APIs to render SVG paths. Alternating shaded vertical bands, generated from x-axis tick positions, help delineate time periods, while axis ticks are manually styled and gridlines added via polygon outlines.

Multi-Line Voronoi

This example shows a multi-line chart of unemployment rates across various U.S. metropolitan areas from 2000 to 2013. An invisible Voronoi tessellation handles mouseover detection, highlighting the nearest line and displaying its value at the cursor position; a checkbox toggles red Voronoi cell borders for inspection. The SVG chart uses d3.line, d3.voronoi, and d3.axisBottom/Left, with data processed from Bureau of Labor Statistics text files into a TSV format.

d3.js line chart with multiple lines and points

This example shows two multi-series line charts overlaid in a single SVG, with each line distinguished by its own path and circular data points. It demonstrates how to map linear scales to x- and y-axes, render gridlines and tick labels, and add interactive hover effects that enlarge points on mouseover. The code uses D3.js v3 APIs including `d3.svg.line()`, `d3.scale.linear()`, and selection methods like `append`, `attr`, and `on`. The data is a hardcoded array of two numeric arrays, with axes and points generated programmatically from the same scales.

Area Chart

This example shows how a hovering cursor over an area chart reveals the underlying data point for that year. The chart visualizes the relationship between age and monthly income using a smooth, semi-transparent blue area. Built with D3.js v7, it renders to an SVG canvas, with the area's path created via `d3.area` and its curve smoothed using `d3.curveMonotoneX`. Interactive tooltips appear on mouseover, displaying the exact year and sales values, with the code also incorporating standard D3 axes and scales for plotting.

area chart

This area chart displays a series of 63 data points showing a fluctuating trend, with a smooth curve drawn through the values and a pink filled region beneath it. Built with Svelte and rendered as SVG, it uses d3.scaleLinear for the x and y axes, along with d3.area and d3.line generators with curveCatmullRom to create the smooth path. A gray overlay rectangle animates across the chart, sliding from left to right via a CSS keyframe animation. The visualization resizes responsively to fill its container using bound client dimensions.
