This multi-line chart displays monthly stock prices for Microsoft, Amazon, and IBM from 2000 to 2010, sourced from a CSV file. The graph automatically generates a color-coded legend, and clicking a legend label toggles the corresponding line’s opacity via a smooth CSS transition. Built with the D3.js library, it uses `d3.time.scale` for the time axis, `d3.svg.line` for plotting, and `d3.nest()` to group data by company symbol, with linear scaling for the price axis.

AI-generated description

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

It is the fourth 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 ability to toggle the lines off and on by clicking on the appropriate legend text.

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

Multi-line graph 4 with v5: Toggle

This multi-line chart displays monthly stock prices for Microsoft, Amazon, and IBM from 2000 to 2010, with each series distinguished by a color-coded legend. Clicking a legend label toggles the visibility of its corresponding line, which fades in or out via a transition. Built with D3 v5, the visualization uses `d3.nest()` to group data by symbol, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.line()` for paths. The underlying data comes from a local CSV file.

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 4 with v4: Toggle

This interactive multi-line chart displays monthly stock prices for three companies (MSFT, AMZN, IBM) from 2000 onward, with a clickable legend that toggles each line’s visibility. Using D3 v4, the code parses CSV data with `d3.csv`, nests records by symbol, and renders SVG paths via `d3.line` and `d3.scaleTime`/`d3.scaleLinear`. Clicking a legend text triggers a 100ms `transition` on the corresponding line’s opacity, dynamically showing or hiding it. The legend colors are assigned with `d3.scaleOrdinal` and `d3.schemeCategory10`.

Multi-line graph 4 with v6: Toggle

A multi-line graph displays monthly stock prices for Microsoft, Amazon, and IBM. D3.js v6 is used to parse CSV data, scale the time and price domains, and render the SVG lines with distinct colors. Clicking a legend label toggles the corresponding line’s opacity via a transition, hiding or showing that company’s data. The example uses `d3.csv`, `d3.timeParse`, `d3.line`, and `d3.scaleOrdinal`.

Multi-line graph 4 with v7: Toggle

This interactive multi-line chart displays monthly stock prices for three companies (MSFT, AMZN, IBM) from January 2000 to March 2010. Users can click legend labels to toggle individual lines on and off, with a smooth opacity transition revealing or hiding each series. The visualization uses d3.csv to load data, d3.group to organize by symbol, d3.scaleOrdinal with d3.schemeCategory10 for colors, d3.line for paths, and d3.axisBottom/axisLeft for axes. Clicking triggers d3.select and transition().duration(100) to animate opacity changes.

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 2: Colours

This multi-line graph displays stock price changes over time for Microsoft, Amazon, and IBM, with each line distinguished by a unique color. The visualization uses the D3.js library (version 3.5) to parse CSV data, scale time and price ranges, and render SVG paths. It applies a categorical color scale via `d3.scale.category10` and assigns colors dynamically to each symbol group from the nested data. The example focuses solely on demonstrating color differentiation among multiple lines, without legends or interactive toggling.
