Three circles are plotted on an SVG canvas according to two linear scales that map x-values (years 2012–2045) and y-values (1–100) to pixel coordinates. The chart scales are stored directly on the SVG element via its `__chart__` property, and each circle references these internal scales using `this.__chart__` within its position attributes. A d3.js v2.7.1 script defines the data points (2015,23), (2024,55), and (2034,12) as animated circular marks, with the visualization demonstrating how chart variables can be internalized as element properties for later access during rendering.

Internalizing chart variables (mod)

Three small circles are plotted as a scatter of three data points, each mapping an `x` and `y` value to screen coordinates. The example demonstrates how to store chart scales on a DOM node by setting an SVG element’s `__chart__` property via `d3.select(...).property`. Inside the property function, two linear scales are built with `d3.scale.linear`, using the parent’s `offsetWidth` and `offsetHeight` for ranges. The circles then access these scales through `this.__chart__` when setting `cx` and `cy`, avoiding closure variables.

D3: Adding values and elements to a chart

This chart displays a dataset of twenty-one coordinate pairs plotted as circles on an SVG canvas. It shows how values and visual elements can be dynamically added and transformed. The example uses D3 v4, implementing scales via `d3.scaleLinear`, axes drawn with `d3.axisBottom` and `d3.axisLeft`, and circles created through `.enter()`. A button triggers a repeating transition animation: the circles swap their x and y coordinates—changing from green to blue and back—using D3 `.transition()`, `.duration()`, and `.delay()` for a sequential, looping effect.

D3: Adding values and elements to a chart

A button click triggers animated transitions for a set of circles plotted against linear x- and y-axes. The chart initially displays points from a fixed data array, then swaps their coordinates and colors in two sequential transitions, cycling in a loop. Built with D3 v4, it uses SVG circles, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`, with chained `transition` calls and delays to orchestrate the repeating visual update.

Visualization Implementation (VI3)

Two scatterplots render 50 randomized data points each using D3.js. The left chart displays circles positioned by linear x and y scales with axes. The right chart clips its circles to a rectangular chart area using an SVG clipPath and includes an interactive text label that updates the chart with new data values on click. Both use d3.svg.axis for ticks and d3.scale.linear for domains.

Animated Chart

A React component renders an SVG bar chart of annual values, with three bars for the years 2020 through 2022. A button click swaps the dataset, triggering a smooth transition where the bars animate their height and vertical position over one second using d3’s `transition`. The chart uses `d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.selectAll` to build and update the visualization within a `useEffect` hook on data changes.

Untitled

Five circles sit on a shared horizontal axis, each sized by a value from the current dataset. A button switches between two data arrays, triggering a one-second transition that repositions circle radii and x-coordinates. Using D3.js v6 with SVG and animation, the code employs data joins, `enter`/`exit` selections, and `transition` to update the visualization. An axis line and a title label (highlighting the active dataset) complete the chart, which renders entirely in the browser.

Concentric circles chart using SVGt

A concentric circles chart displays two nested circles centered at the origin, rendered as an SVG viewBox with a range of -100 to 100. The outer circle has a radius of 50 and a fill of rgb(0,122,176), while the inner circle has a radius of 10 and a fill of rgb(162,207,225). The example uses the SVG `<circle>` element directly within an inline `<svg>` tag, with no JavaScript libraries or external data sources involved. It demonstrates a minimal, static visualization of hierarchical proportions through simple geometric layering.

This example shows a line chart of population values from 2005 to 2015, drawn as an SVG path using D3 v4’s `d3.line` and `d3.scaleTime`/`d3.scaleLinear` scales. The data is loaded from `data.json` with `d3.json` and parsed via `d3.timeParse`. A hover interaction uses a transparent overlay rectangle, `d3.mouse`, and `d3.bisector` to find the nearest year, then updates a focus circle, dashed hover lines, and a value label via direct SVG attribute manipulation. The y-axis labels are formatted in thousands with a custom tick format.
