Four horizontal bars illustrate linear scaling in D3.js v4. Each rectangle’s width maps a value from the fixed data array `[120,40,5,100]` through a `d3.scaleLinear` domain to a pixel range, while a second `d3.scaleLinear` interpolates fill color from red to blue across the same values. The SVG canvas is 500 by 500 pixels, with bars stacked at 100-pixel intervals. This example demonstrates how a single quantitative scale can drive both geometry and color encoding.

This example shows four horizontal bars rendered as SVG rectangles, with their widths proportional to values in a static data array of [20, 40, 50, 60]. The code uses a linear scale (`d3.scale.linear`) to map data values to pixel widths, then appends rectangles via `d3.selectAll("rect").data().enter()`. Each bar is positioned vertically by index, and all bars share a steelblue fill. The visualization duplicates the same bar-drawing block twice, though only the first set of rectangles is visibly rendered.

Three vertical rectangles display a small bar chart from a hardcoded data array of [20, 40, 50]. Each bar’s width is proportional to its value, multiplied by ten, while height is fixed at 50 pixels and vertical positions step by 100 pixels. d3.v4’s selection, data join, and enter methods render the SVG rectangles. The code also contains commented-out attempts at circles and d3.set usage. The page uses steelblue fill for the bars on a 500‑by‑500 SVG canvas.

oefening groups axes

A simple bar chart displays four values from a hardcoded array. Linear scales map data values to bar widths and a color range from red to blue. D3 v4's `d3.axisTop` adds a top-oriented axis with five ticks based on the width scale. The SVG rendering uses `rect` elements with fixed height and vertical spacing.

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.

d3js Exercice 2 - Scales

This example demonstrates how d3.scaleLinear maps input values from a domain to a range, showing the output for inputs of 0, 10, and 20, then extending beyond the interval to reveal unbounded behavior. It then applies the clamp(true) method to the scale, which restricts outputs for out-of-range values like -10 and 200. Built with D3 v4, the code writes results directly to the document via document.writeln, and comments suggest experimenting with invert, power, log scales, or a color range.

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.

Classical Scales

This visualization showcases a comprehensive set of D3.js v2.10 scales through a series of horizontal axes, each paired with a descriptive label. Linear, logarithmic, power, square-root, quantile, quantize, threshold, and identity scales are demonstrated, with the log and power scales shown across different domain ranges to illustrate their behavior. The example also highlights tick subdivision options, including numeric, boolean, and string arguments, which is particularly notable because vanilla D3 v2.10 does not support function-based parameters for tick subdividing. The SVG renderer displays the axes with a glowing filter effect and the layout is fixed to 1500 pixels in height to accommodate the many examples.
