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.

AI-generated description

This is used as an example in the book D3 Tips and Tricks v6. 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 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 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 1 with v6: Lines

This visualization shows monthly stock prices for Microsoft, Amazon, and IBM from 2000 to 2010 as a multi-line graph. Using D3 v6, it loads CSV data and groups the entries by company symbol with `d3.group` to draw each series as a separate SVG path. The chart employs `d3.scaleTime`, `d3.scaleLinear`, and `d3.line` for axes and line generation, with `d3.extent` fixing the domain. Axis rendering uses `d3.axisBottom` and `d3.axisLeft`.

Multi-line graph 2 with v7: Colours

This chart displays monthly stock prices for three companies (MSFT, AMZN, IBM) from 2000 to 2010, using multiple colored lines to represent each symbol. The visualization uses D3.js v7 to read a CSV file, parse dates with `d3.timeParse`, and group data by symbol using `d3.group`. Lines are drawn with `d3.line` and colored via `d3.scaleOrdinal` with the `schemeCategory10` palette. The graph includes time-series axes created with `d3.axisBottom` and `d3.axisLeft`, rendering everything as SVG elements.

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.

Multi-line graph 2 with v6: Colours

This chart displays monthly stock prices for Microsoft, Amazon, and IBM from 2000 to 2010 using a multi-line graph, with each company's price trend distinguished by a unique color from the `d3.schemeCategory10` palette. The data is loaded from a CSV file using `d3.csv()`, then parsed and grouped by symbol with `d3.group()`. Lines are drawn as SVG paths via `d3.line()`, with colors assigned dynamically from a `d3.scaleOrdinal` color scale based on each group's index, while axes are rendered using `d3.axisBottom` and `d3.axisLeft`.

Multi-line graph 1 with v7: Lines

This multi-line graph displays monthly stock prices for Microsoft, Amazon, and IBM from 2000 to 2010, with each company represented by a separate line. The visualization uses D3 v7’s `d3.group` function to nest data by symbol, then draws each line using the `d3.line` path generator. Data is loaded from a CSV file via `d3.csv`, with dates parsed using `d3.timeParse` and scales set with `d3.scaleTime` and `d3.scaleLinear`. Axes are rendered as SVG elements using `d3.axisBottom` and `d3.axisLeft`.
