A D3 example demonstrates a linear scale mapping a data domain of 1 to 5 into a pixel range of 0 to 200, driving the x-position of text elements in an SVG. Using `d3.select` and `scale.attr`, the code binds arrays of numbers to text nodes, updating their position and fill color on a five-second timer. The `enter`, `update`, and `exit` selections manage the text lifecycle, showing red, blue, green, cyan, and magenta labels as the dataset changes. This illustrates data joins with `d3.scale.linear` and `svg.append`.

D3 Scale

This example demonstrates how D3 scales map input data to visual output, using a linear scale to position circles along the x-axis and a multi-domain color scale to assign fill colors. The circles represent values from -10 to 10, with colors transitioning from red through gray to blue. It renders as an SVG using d3.scaleLinear for both positioning and color interpolation, with data bound through d3.select and .join(). The code references D3 v7 scale types in utils.js, including scaleTime, scaleBand, and scaleOrdinal, though only linear scales are actively applied.

D3 Scale Functions

This example demonstrates how D3 scale functions map input data values to visual output positions. It plots a set of numeric data points as circles along a horizontal axis, with each value labeled above its corresponding circle. The code uses `d3.scaleLinear()` to map the domain (0–10) to a pixel range, and renders the result as SVG elements. An axis is added using `d3.axisBottom()`, and the utility function `getScale` supports multiple scale types, including `scaleSqrt`, `scaleLog`, and `scaleBand`, though only linear is actively applied here.

scale

This example demonstrates the foundational concept of D3 scales by computing and logging values from linear, square root, and time scales, then calculating the extent of a small dataset and applying a linear scale with a nice domain. It uses the d3 v7 library, importing scaleLinear, scaleSqrt, and scaleTime from d3, and renders to a blank SVG canvas. The code defines explicit domains and ranges to show how input values map to output pixel positions, with a dataset of five numeric values and an extent-based domain.

D3: Drawing Scale

This example demonstrates how D3’s linear and square-root scales translate raw data coordinates into pixel positions and circle radii. It plots an array of 11 `[x, y]` pairs as circles and red text labels on an SVG canvas. The code uses `d3.scaleLinear()` for both the x and y axes, and `d3.scaleSqrt()` for sizing the circles proportionally. The scales are configured with custom domains and output ranges, with padding applied to keep marks inside the 500×300 viewport. Data is rendered statically, with labels showing the original coordinate values.

using of scale, scaleLinear(), scaleOrdinal()

This example demonstrates how D3 scaling functions map input domains to output ranges for both numeric and categorical values. A `scaleLinear()` maps values 0–3 to a pixel range of 0–300, logging transformed results to the console. A `scaleOrdinal()` assigns colors from an array to categorical domain values, and the code appends four div elements to the DOM, coloring each with a different color via D3 selections. The page is a minimal HTML document using d3.v5 and relies on CSS styling through inline `.style` calls.

D3 Scale Function PRactice

This example demonstrates D3 scale functions by mapping a small array of numeric values to positions along an SVG axis. It renders circles and labels on a horizontal line using a linear scale, then displays the corresponding axis with `d3.axisBottom`. The code imports a custom `getScale` utility from `utils.js` that switches between D3’s scale types—including `scaleLinear`, `scaleSqrt`, `scaleLog`, and others—although only the linear scale is actively applied. The visualization uses SVG rendering with a fixed 960×500 canvas and D3 v7 via `bundle.js`.

scale

This example demonstrates how D3’s linear scale maps a continuous domain to a fixed pixel range, with an interactive slider adjusting the domain’s maximum value from 20 to 1,000. The visualization renders two SVG axes: a blue-tinted grid of minor ticks and a black major axis, both regenerated on slider input via `d3.svg.axis()` and a `redraw()` function. The code uses D3 v3, SVG rendering, and a range input element to drive the scale’s domain, while CSS styling differentiates gridline hierarchies and the axis appearance.

D3 Scale - ScaleLog

This example demonstrates how a logarithmic scale maps data values across an SVG canvas. It places six text labels at positions calculated by a `d3.scaleLog()` function, with a domain spanning from 10 to 100,000 and a range of 0 to 700 pixels. The visualization highlights how log scales compress large numerical ranges, showing labels for 0, 10, 100, 1,000, 10,000, and 100,000 at increasing intervals. The code uses D3 v7’s `scaleLog`, `scaleLinear`, and `scaleSqrt` definitions, rendering the output as SVG text elements.
