A scatterplot displays ten data points as circles with adjusted radii, each labeled with its coordinate pair. The plot uses D3.js version 4.5.0 scaleLinear functions to map x and y values to screen positions, while a third scale maps the second coordinate to circle radius between 2 and 5 pixels. The SVG visualization renders with red text labels and sans-serif font, demonstrating how D3 scales control both position and size.

36. D3 Scale Plot

A scatterplot positions ten data points as circles on an SVG canvas using linear scales. The `d3.scaleLinear()` API maps the dataset’s x- and y-value domains to pixel ranges of 500 by 100, while circle radii derive from the square root of the height minus each y-value. Red text labels display the original coordinate pairs.

40. D3 Scale Plot Large

This example presents a scatterplot of eleven data points using D3.js version 4.5.0, rendered as SVG circles with red text labels. Each point’s x and y coordinates are mapped to the plot area through linear scales (`d3.scaleLinear`), while a third scale determines the circle radius based on the y-value. The chart is resized to a larger 500x300 pixel canvas with padding, and labels display the raw coordinate pairs alongside each point.

39. D3 Scale Plot Big

A scatterplot maps a small dataset of eleven coordinate pairs onto an SVG canvas, with circle positions scaled by d3.scaleLinear functions for the x- and y-axes, and circle radii scaled by another linear scale based on the y-value. Each point is labeled with its original coordinates in red sans-serif text. The chart demonstrates basic scaling and data-binding patterns within D3 version 4.5.0, using standard selection and enter-append methods to generate SVG elements from the array. No axes, tooltips, or interactivity are included.

D3 Scale Plot Large

This example shows a scatterplot of 11 data points, each represented by a circle with a red text label showing its x,y coordinate. The visualization uses D3.js v3 scale functions (`d3.scaleLinear`) to map the data values to SVG circle positions and radii, with padding applied to the plotting area. The SVG rendering is created programmatically by appending circles and text elements to the document body, demonstrating how scales handle a large data value (600,150) without manual axis adjustment.

41. D3 Scale Plot Sqrt Scale

A scatterplot displays eleven data points as circles, with a square root scale determining circle area based on the y-value. The visualization uses D3 v4.5.0 with `d3.scaleLinear` for x and y positioning and `d3.scaleSqrt` for radius mapping. Each circle includes a red text label showing its original coordinates. The SVG-rendered chart demonstrates how this scale creates proportionally smaller circles for lower values.

33. D3 Scatterplot Sqrt

A scatterplot displays ten data points on a 500-by-100 SVG canvas, with each circle positioned according to its x and y coordinates. The circle radius is computed as the square root of the difference between the canvas height and the y-value, creating larger points toward the bottom. Built with D3.js version 4.5.0, the visualization uses the `selectAll`, `data`, and `enter` pattern to bind the dataset and append circles, setting the `cx`, `cy`, and `r` attributes through anonymous functions.

45. D3 Axes Y

A scatterplot displays 11 data points as circles, with each point labeled by its x,y coordinates in red text. The visualization implements two linear scales for the x- and y-axes using `d3.scaleLinear()`, plus a square-root scale (`d3.scaleSqrt()`) to encode the y-values as circle radii. Vertical and horizontal axes are added using `d3.axisBottom()` and `d3.axisLeft()`, both with five ticks, and rendered as SVG groups. The chart uses a 500×300 SVG canvas with explicit padding.

32. D3 Scatterplot

Ten fixed data points appear as circles in an SVG scatterplot, with position determined by x/y coordinates from a two-dimensional array. The example uses D3 version 4.5.0 to select the body, append an SVG element, and bind the dataset through the data join pattern, setting circle attributes with anonymous functions. Static rendering shows the basic scatterplot construction without scales or axes.
