This example displays multiple stock price time series in a single SVG line chart, using D3 v4 to plot data for Microsoft, Amazon, and IBM from January 2000 through March 2010. The visualization distinguishes each company’s line with a categorical color from `d3.schemeCategory10` and adds an automatically generated legend, positioning text labels evenly across the chart’s width. The data, loaded from a CSV file, is parsed with `d3.timeParse` and nested by symbol using `d3.nest` to create separate lines. Axes are rendered with `d3.axisBottom` and `d3.axisLeft`, while scales are defined via `d3.scaleTime` and `d3.scaleLinear`.

AI-generated description

This is a derivative of the simple d3.js graph in v4 used as an example in the book D3 Tips and Tricks v4. The stock data was sourced from Mike Bostock's small multiples example.

It is the third graph in a series that is building a multi-line graph that incorperates an automatically developed legend and a system that can toggle the lines off and on as desired.

This version is demonstrating the addition of a legend to the graph.

The graph should be taken in context with the text of the book which can be downloaded for free from Leanpub.

Multi-line graph 2 with v4: Colours

A multi-line graph displays stock prices over time for Microsoft, Amazon, and IBM, with each company’s series drawn in a distinct color from a categorical palette. The visualization uses the D3 v4 library, parsing dates with `d3.timeParse` and rendering lines as SVG paths via `d3.line`. Data is loaded from a CSV file, grouped by symbol with `d3.nest`, and colored using `d3.scaleOrdinal` with the `d3.schemeCategory10` palette. The chart includes a time-based x-axis and linear y-axis, with the line colors assigned dynamically to distinguish each stock series.

Multi-line graph 1 with v4: Lines

This example shows a multi-line graph comparing the monthly stock prices of Microsoft, Amazon, and IBM from 2000 to 2010. It uses D3 v4 with SVG rendering, parsing dates with `d3.timeParse` and nesting the CSV data by symbol via `d3.nest` to draw a separate line for each company. The lines are styled with a steel blue stroke, and both axes are generated using `d3.axisBottom` and `d3.axisLeft`. The data originates from a CSV file, and the code demonstrates grouping data to create multiple line series.

Multi-line graph 3 with v5: Legend

This example shows a multi-line chart tracking monthly stock prices for three companies (MSFT, AMZN, IBM) from 2000 to 2010, with a color-coded legend placed below the x-axis. Using D3 v5, it nests the CSV data by symbol, draws each series as an SVG path, and assigns colors via `d3.scaleOrdinal` with `d3.schemeCategory10`. The legend labels are dynamically positioned and colored to match each line, and axes are generated with `d3.axisBottom` and `d3.axisLeft`.

Multi-line graph 3 with v5: Legend

This interactive multi-line chart displays monthly stock prices for Microsoft, Amazon, and IBM from January 2000 to March 2010, with each series distinguished by a color from the Category 10 palette. Built with d3.v5, it renders lines as SVG paths and includes a legend beneath the plot, where each company name is color-coded to match its line. The dataset, sourced from Mike Bostock’s small multiples example, is grouped by symbol using d3.nest(), with scales defined by d3.scaleTime and d3.scaleLinear for the axes.

Multi-line graph 3 with v7: Legend

This multi-line graph shows monthly stock price changes for Microsoft, Amazon, and IBM from 2000 to 2010, with a categorical legend labeling each company’s colored line. Using d3.v7, the code parses dates with `d3.timeParse`, groups the CSV data by symbol via `d3.group`, and applies a `d3.scaleOrdinal` color scheme. Each path is drawn with `d3.line` and `d3.scaleTime` and `d3.scaleLinear` axes, while legend text is positioned evenly along the bottom using computed spacing.

Multi-line graph 3 with v6: Legend

A multi-line graph displays monthly stock prices for MSFT, AMZN, and IBM from 2000 to 2010, with each series colored distinctly via a categorical scale. The visualization uses D3 v6 APIs such as `d3.csv`, `d3.timeParse`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.line`, rendering to SVG. A legend is automatically generated beneath the chart, spacing labels evenly and matching each company's line color, with data sourced from Mike Bostock's small multiples example.

Multi-line graph 4 with v4: Toggle

This multi-line graph displays monthly stock prices for Microsoft, Amazon, and IBM from January 2000 to March 2010, with each company's price trend drawn as a separate colored line. The chart uses D3.js v3 with SVG rendering, parsing dates from a CSV file and applying a time-scaled x-axis. The code nests the data by stock symbol using `d3.nest()`, assigns each line a color from `d3.scale.category10()`, and draws the paths with `d3.svg.line()`.

Multi-line graph 3: Legend

Three stock price time series are plotted as separate colored lines, with a legend beneath the x-axis identifying each series by its symbol (MSFT, AMZN, IBM). The SVG chart is built with D3.js, using `d3.nest` to group monthly CSV data by symbol and a categorical color scale to assign line and legend colors. Axes are generated with `d3.svg.axis`, and data spans January 2000 through March 2010.
