A scatterplot-style visualization maps four series of quarterly literacy and line-level scores as static steelblue circles, with each circle’s vertical position determined by its Q1 value. The chart uses d3.csv to load the dataset, d3.scaleLinear for both x and y axes, and d3.axisBottom plus d3.axisLeft to render the axes. All circles share a fixed radius of 20 pixels, and the SVG rendering is driven by standard d3 selections and data joins.

The d3 test

This example shows a simple scatter plot of four data points, each represented by a steelblue circle, positioned along linear x and y axes. The data is a hardcoded array of coordinate pairs. The visualization is built with D3 v2, using `d3.scale.linear` for the x and y scales, `d3.svg.axis` for the axes, and SVG `circle` elements appended to a group. The chart is sized with margins, and the axes are drawn on the bottom and left of the plot.

Anscombe's Quartet with simple-statistics and d3js v4 -

Anscombe's Quartet is visualized as four separate scatterplots, each displaying a series of 11 data points loaded from a CSV file. The charts share identical axes, scales, and styling—pink circles on a cream background—and each is labeled Series 1 through 4. Using the simple-statistics library, the same summary statistics (mean, sample variance, and correlation coefficient) are calculated for every series and printed beneath each plot, showing nearly identical values. The d3.js v4 code also fits and draws a light-blue regression line per plot, emphasizing how the four datasets, though statistically similar, have very different graphical structures. The example is implemented entirely in SVG, with no animation, and demonstrates the importance of visualizing data before relying on descriptive statistics.

d3 Test visualization with scatterplot

This d3.v5 scatterplot renders red, semi-transparent circles on a large SVG canvas, with axis labels, tick marks, and a title styled via CSS. The chart uses `d3.axisBottom` and `d3.axisLeft` to generate the axes, and the data is hard-coded in the JavaScript file, plotted via `d3.selectAll` and `d3.attr` for positioning. The visualization emphasizes simplicity, with all marks sharing a uniform color and opacity.

Q2 D3

A scatter plot visualizes the relationship between hours studied and exam scores across 150 students, using D3 v7 to load CSV data and render SVG circles mapped through linear scales. The chart includes labeled axes, a bold title, and semi-transparent steelblue points sized at 4 pixels. Data comes from a local `study_scores.csv` file, with axes and scales configured via `d3.scaleLinear`, `d3.extent`, and `axisBottom`/`axisLeft`.

Basic starter code for many simple D3 charts, v4

A scatterplot displays Anscombe’s Quartet, with points labeled by their x- and y-coordinates and grouped by quartile. The chart uses D3 v4’s `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisRight`, with axes positioned on the right and bottom of an SVG canvas. Data loads from a tab-separated file via `d3.tsv`, and the x- and y-domain extents are updated based on the loaded values. Each point is drawn as a `circle` with a sibling `text` label, both grouped in a transformed `<g>` element.

d3.js Scatter test page

This page demonstrates a simple scatter plot using D3.js v4, visualizing the relationship between category and score for two data types (Alpha and Beta). The data is loaded from a TSV file, cleaned, and augmented with a horizontal jitter to separate overlapping points. The chart includes axes, gridlines, a legend, and interactive tooltips that display category, score, and type on hover. Semi-transparent colored circles are rendered in SVG, with colors assigned by data type via a categorical color scale. The visualization was updated to D3 v4 by annelid, based on 1wheel's original block.

scatterplot using d3

A scatterplot displays name-number pairs from a local CSV file, mapping names to the y-axis and numeric values (scaled by 1000) to the x-axis using d3.scalePoint and d3.scaleLinear. Circles are rendered via SVG with fixed radius and semi-transparent steelblue fill. The code imports d3 functions like select, csv, and axisBottom, and includes a formatted x-axis with tick size and a custom text label, demonstrating basic D3 v6 data binding and margin-based layout.

d3 circles

This example displays a scatterplot of 50 randomly generated data points, each positioned by x and y coordinates on linear scales. The circles transition from teal to black with varying radii based on the y-value. Clicking the prompt above the chart generates new data points, triggering animated transitions that update circle positions, radii, and the axes using d3.axisBottom and d3.axisLeft. The visualization uses d3.v4 with SVG rendering, including a clipPath to contain the circles within the chart area.
