This visualization demonstrates the difference between raw data points connected by a line and a calculated trend line overlaid on the same chart. It shows how a simple linear regression fits the given data sequence, with the raw path in red and the trend line in green. The code uses D3.js v2 to build an SVG visualization, mapping input data indices to x-coordinates and values to y-coordinates via linear scales. It computes the least-squares regression line by calculating the slope and intercept from the data, then renders both lines using `d3.svg.line` to create the path geometry.

Gist bb8fddc4a5fc3cc60c99

A line chart maps a small array of ten numbers to an SVG path, showing how the values fluctuate across a linear sequence. The visualization uses a red, unbroken polyline to emphasize the shape of the data, with the y-axis scaled from the data’s minimum to maximum and the x-axis evenly spaced by index. The code creates the chart using d3.scale.linear for both axes and d3.svg.line to generate the path, which is appended to an SVG container via d3.select and datum. The fixed width and height of 500 pixels define the plotting area, while the stroke and fill styles come from a CSS class.

Data Visualisation with D3 - Pseudo Charts (Line)

This example shows a minimal line chart built with raw SVG, not a traditional D3.js construction. The visualization plots five data points connected by a thick black path, where the stroke width and rounded line joins visually emphasize the connecting segments. The code uses an inline SVG element with a `path` that defines the line’s geometry via `M` and `L` commands. Although the title mentions D3, no D3 library is actually loaded; instead, the implementation relies solely on native SVG properties like `stroke`, `stroke-width`, and `stroke-linejoin` to create the appearance of a line chart. The data is hardcoded as coordinates in the path definition.

d3.js line chart with multiple lines and points

This example shows two multi-series line charts overlaid in a single SVG, with each line distinguished by its own path and circular data points. It demonstrates how to map linear scales to x- and y-axes, render gridlines and tick labels, and add interactive hover effects that enlarge points on mouseover. The code uses D3.js v3 APIs including `d3.svg.line()`, `d3.scale.linear()`, and selection methods like `append`, `attr`, and `on`. The data is a hardcoded array of two numeric arrays, with axes and points generated programmatically from the same scales.

timeline - trend

The visualization demonstrates how a single outlier or a user-dragged point dramatically alters a least-squares trend line. It shows a scatter plot of a 20-point time series, where each blue dot can be moved with the mouse to immediately recalculate and redraw the steel-blue regression line. A timeline path connects the points, and buttons allow inverting the trend or creating an outlier. Built with D3.v3, it uses `d3.behavior.drag`, `d3.svg.axis`, and `transition` functions to animate updates, with data loaded from a CSV via `d3.csv`.

simple line chart

This example shows a simple line chart that visualizes a randomly generated dataset of thirty points, with each point’s y-value incrementing by a random offset from the previous point. The chart displays the overall trend of the series, with a final value label and x-axis tick labels for each data index. The code uses D3 v3 to append an SVG, create linear scales for the x and y axes, and draw the line via `d3.svg.line()`. The data is generated inline using JavaScript’s `Math.random()` within a `d3.range()` map, and the chart is rendered as an SVG path with a black stroke.

Basic Chart, simple dataset

This example displays two overlaid line charts, each plotting a distinct series from a tab-separated dataset against the same x-axis. The visualization uses D3 v5 to load data via `d3.tsv`, applies linear scales (`d3.scaleLinear`) to map x and y values, and renders the series as both green and steel-blue circles and connected paths using `d3.line`. The SVG output is transformed by a 25-pixel offset, while the dataset contains paired y-values across nine x-points.

fresh block

This example shows a simple line chart of 21 random data points, with each point represented as a circle. The visualization uses D3.js v4 to generate an SVG, with a black line connecting the dots and interactive hover effects that turn the circles red on mouseover and fade back to black on mouseout. The code applies the margin convention, scales the data with `d3.scaleLinear`, and uses the `d3.line` generator to draw the path. Axes are rendered with `d3.axisBottom` and `d3.axisLeft`, and the chart fills the browser window.

D3 Page Template

This example demonstrates a simple SVG line chart template using D3.js, where a red polyline connects six data points across a 500x400 canvas. The visualization shows a basic yet effective pattern for plotting series data, with points positioned at varying y-coordinates to create a descending then ascending trend. The code relies on D3 v7 loaded via CDN and constructs the line using an SVG path element with the `d` attribute, specifying coordinates through a path string. The `stroke` and `stroke-width` attributes control the visual styling, while `fill="none"` keeps the area under the curve transparent. This serves as a minimal starting template for building more complex D3 visualizations in plain HTML.
