This example demonstrates a multi-line chart with two distinct y-axes, plotting both the close and open values from a CSV dataset over time. It uses D3 v5 to render SVG elements, with a time-scaled x-axis and separate linear scales for the left and right axes, each styled with different text colors. The chart follows a reusable module pattern inspired by Mike Bostock’s “Towards Reusable Charts” and the Pro D3 book, creating maintainable, modular visualizations. The code builds scales, axes, and lines programmatically, positioning the right axis and its corresponding line alongside the left one.

Simple Line Chart with Multiple lines and two different axes:

A vanilla HTML implementation of a d3Noob's V5 examples.

Examples Malcolm Maclean's (d3noob) great book "D3 Tips and Tricks v5.x Interactive Data Visualization in a Web Browser" (https://leanpub.com/d3-t-and-t-v5).

It is derived from Mike Bostock's Towards Reusable Charts (https://bost.ocks.org/mike/chart/) as the source of the foundational principles. But uses the ProD3 pattern (Pro D3.js Use D3.js to Create Maintainable, Modular, and Testable Charts by Marcos Iglesias https://www.apress.com/gp/book/9781484252024) as the basis for the charts.

d3NoobV5 Reusable Examples - MultiLine Chart

A reusable multi-line chart renders two time-series lines from a CSV dataset, plotting date against closing and opening values. The visualization demonstrates a modular chart architecture using D3 v5's SVG rendering, with scales, axes, and gridlines constructed via `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` within a pattern inspired by Mike Bostock's reusable charts. The chart draws two distinct lines from the same data columns, showing how additional series can be added to the reusable component.

d3NoobV5 Reusable Examples - MultiLine Chart with lines labelled

This example shows a multi-line chart that plots two time-series from a small CSV dataset, with each line labeled directly on the chart. Using the D3.js v5 library, it defines reusable chart components through a module pattern, building SVG output with scales for date and linear values. The code constructs axes, gridlines, and lines via `d3.axisBottom`, `d3.axisLeft`, `d3.scaleTime`, and `d3.scaleLinear`, while the data is accessed using extractor functions. The chart is based on Malcolm Maclean's "D3 Tips and Tricks" examples, adapted into a modular, testable structure following the ProD3 pattern.

d3NoobV5 Reusable Examples - MultiLine Chart (adjusted) with lines labelled

This example shows a multi-line chart with two labeled lines, plotting date against two numeric values from a CSV dataset. The chart uses D3.js v5 to render SVG elements, with scales mapping time and linear values. A reusable chart module builds axes, gridlines, and lines via `d3.axisBottom`, `d3.axisLeft`, and `d3.scaleTime`, while `data.columns.slice(1).map` transforms the raw CSV data for plotting. The visualization highlights two series, with labels drawn after the lines, and a title and axis labels included.

d3NoobV5 Reusable Examples - Simple Line Chart

This example displays a simple line chart of stock closing prices over time, with a steelblue stroke on an SVG canvas. It implements a reusable chart module using D3 v5, following the ProD3 pattern for maintainable structure. The code defines scales with `d3.scaleTime` and `d3.scaleLinear`, renders axes via `d3.axisBottom` and `d3.axisLeft`, and draws the line with `d3.line`. Data is loaded from a CSV file containing date and close values, with axis labels and a title included.

d3NoobV5 Reusable Examples - Line Chart with Grid Lines

A reusable line chart renders financial closing prices from a CSV file, mapping dates on a time scale and values on a linear scale. The visualization includes labeled axes, a title, and light gray grid lines created with d3.axisBottom and d3.axisLeft using negative tick sizes. Built with d3.v5 and SVG, the code applies the ProD3 pattern for modular chart components, following Malcolm Maclean’s D3 Tips and Tricks and Mike Bostock’s reusable chart principles.

d3NoobV5 Reusable Examples - Area Chart

This example demonstrates a reusable area chart built with D3.js v5, showing stock closing prices over time from a CSV dataset with date and close columns. The chart renders an SVG containing a lightsteelblue area path and an overlaid steelblue line, using d3.area() and d3.line() with time and linear scales. Axes are generated via d3.axisBottom and d3.axisLeft, while the chart’s modular structure follows the Pro D3 pattern, separating scales, axes, and drawing functions into reusable components.

d3NoobV5 Reusable Examples - Dotted Line Chart

This example shows a dotted line chart of stock closing prices over time, using a reusable chart module pattern derived from d3noob’s D3 tips and the Pro D3 book. The SVG renderer uses `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.line` with a `stroke-dasharray` attribute to create the dotted effect. Data comes from a CSV file with date and close values.

d3NoobV5 Reusable Examples - Scatter Chart

A d3NoobV5 reusable scatter chart visualizes a date-close value dataset from a CSV file, plotting green circular dots over a steelblue line graph with labeled time and linear axes. Built with d3.v5 and SVG rendering, it uses `d3.scaleTime` and `d3.scaleLinear` for scales, `d3.axisBottom` and `d3.axisLeft` for axes, and reusable chart pattern principles from Mike Bostock and Marcos Iglesias. The example demonstrates modular code structure with margin conventions and separate build/draw functions.
