This example shows a simple D3 scatterplot that displays each point’s coordinate values as red text labels directly beside the corresponding circles. The code uses a fixed dataset of ten [x, y] pairs and an SVG rendering approach, with d3.select and data joins to append both circle and text elements. The circles’ radii are calculated as the square root of the height minus the y-coordinate, while the labels reveal the raw data values in an 11-pixel sans-serif font. The visualization is static, with no animation or interactive behavior.

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.

D3: A simple scatterplot with SVG

This example shows a simple scatterplot of ten data points, each rendered as an SVG circle and labeled with its coordinates. The chart uses the D3.js library (version 3) to programmatically build the visualization: first, the code creates an SVG canvas via `d3.select` and `.append("svg")`, then uses `.selectAll("circle").data(dataset).enter()` to map the 2D array of `[x, y]` values to circle positions and radius sizes. Red text labels are added in a similar declarative manner, with font styling applied through attribute setters. The raw coordinate pairs come from a hardcoded dataset, and the circle radius is computed from the data point’s height, creating a visual encoding of magnitude.

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.

D3: Drawing a Scatter Plot

This example displays a basic scatter plot of ten data points, each represented by a circle and a red text label showing its coordinates. The visualization uses D3.js v7 to append SVG circles and text elements to the document body. Circle radii are calculated as the square root of the difference between the plot height and the y-coordinate, creating a size variation tied to vertical position. The chart is drawn with a 500 by 100 pixel viewport, using the data array directly as the source for positioning.

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.

44. D3 Axes Clean

This example shows a scatter plot of coordinate pairs plotted with D3.js version 4.5.0. It renders circles and red text labels in an SVG canvas, using `d3.scaleLinear` for x and y axes and `d3.scaleSqrt` for circle radius sizing based on the y-value. The X-axis is customized with `d3.axisBottom` and `tickValues` to display only four specific tick marks (0, 100, 250, 600), demonstrating how to reduce axis clutter.

39. D3 Scale Plot Radii

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.

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.
