A multi-line chart of stock prices uses D3 v4 to render SVG paths for each symbol. End-of-series labels overlap, so a simple constraint relaxation algorithm iteratively adjusts each label's vertical position until all are spaced at least 14 pixels apart, triggering an animation. Voronoi overlay paths enable mouseover interactions, while the final labels appear only after this relaxation converges, using data from stocks.tsv.

Constraint Relaxation - Prices

This example visualizes monthly average price histories for multiple commodity series, drawing small-multiple line charts across a grid. Unlike typical faceted plots, the chart labels are positioned using a constraint relaxation algorithm borrowed from the Dorling Cartogram approach: each label is simulated as a charged particle that repels neighbors and is pulled toward its target data point, iteratively reducing overlaps. The result is a clean, readable set of annotated mini time-series charts, with SVG rendering and D3 v2, showing how constraint-based layout can untangle dense labeling in small multiples.

Labels on multiple lines v4

This example shows a multi-line chart with two time-series lines for stock open and close prices, with labels placed directly at the end of each line. The labels “Open” and “Close” are positioned manually using SVG text elements, colored to match their respective lines (red and steelblue), and anchored to the final data points. The visualization uses d3.csv to load the data, d3.timeParse to parse dates, and d3.line with d3.scaleTime and d3.scaleLinear to render the paths in an SVG canvas.

Labels on multiple lines v5

Two time series lines show daily open and close stock prices from a CSV file, with each line labeled at its final value on the right edge of the chart. The graph uses d3.line to generate the paths, d3.scaleTime and d3.scaleLinear for the axes, and d3.axisBottom and d3.axisLeft to render them. Text labels for “Open” and “Close” are placed manually via SVG text elements, positioned using the y-scale at the last data point. The example is built with D3 v5 and renders to SVG.

stock

A multi-line chart animates banking stock prices over time, with each series plotted in its own horizontal band and labeled by symbol. The visualization first draws lines progressively using a `d3.timer`, then transitions into horizon charts by stacking filled areas with a `clipPath`. Data is loaded via `d3.csv` from a gist and parsed with `d3.time.format`. The SVG rendering uses `d3.svg.line`, `d3.svg.area`, and `d3.scale.linear` to map dates and prices, with color assigned by `d3.scale.category10`.

Labels on multiple lines v6

This example shows two time-series lines of stock data, one for "Close" and one for "Open," plotted over dates in April and May 2012. Each line is labeled directly at its right endpoint, with the "Open" label in red and the "Close" label in steelblue, matching the line colors. The visualization uses d3.version 6, along with d3.timeParse, d3.scaleTime, d3.scaleLinear, d3.line, and d3.axisBottom/axisLeft, to render an SVG chart. Data is loaded from a CSV file with d3.csv, and the paths are drawn using the d3.line generator with separate `valueline` and `valueline2` functions.

Multi-line graph 4: Toggle

This multi-line graph displays monthly stock prices for multiple companies over time, with each line assigned a unique color via D3's category10 scale. The data is loaded from a CSV file, nested by stock symbol, and rendered as separate SVG paths using D3’s time scale for dates and linear scale for prices. A legend with clickable text labels allows users to toggle individual lines on and off; clicking a legend entry fades the corresponding line to an opacity of zero or restores it to full opacity with a 100ms transition. The chart includes axes and a dynamic color assignment, with the toggle functionality demonstrated as the fourth iteration in a series focused on building interactive multi-line graphs.

Untitled

This visualization displays multiple stock price trends over time as colored lines on a shared time-series chart. The code loads data from a CSV file, parses dates, and groups entries by symbol using `d3.group`. It renders SVG paths with a steelblue stroke overridden by a categorical color scale (`d3.scaleOrdinal` with `d3.schemeCategory10`), and adds axes via `d3.axisBottom` and `d3.axisLeft`.

05_D3 Stock show

This example animates a small multi-line stock chart, showing three fictional symbols (AIC, Mada, VIZ) over time. The animation initially draws each line progressively, then transitions into a “horizon” view, where each series is stacked and colored to show its magnitude and direction. The code uses d3.csv to load the data, d3.nest to group by symbol, and d3.svg.line and d3.svg.area to define the shapes. Animated transitions are driven by d3.timer and the transition method, with SVG elements for rendering.
