This example demonstrates a reusable bar-code chart built with D3 v5, following the ProD3.js pattern for modular, maintainable visualizations. It renders a time-based dataset as vertical black lines over a white background, with each line’s x-position determined by a date value via `d3.scaleTime`. The chart initializes with a back bar drawn as a white rectangle, then appends and transitions line elements using SVG and `transition().duration(300)`. The code includes update functions for data and fill color, reflecting the reusable chart architecture derived from Mike Bostock’s and Rob Moore’s patterns.

AI-generated description

Simple Bar Chart example:

A vanilla HTML implementation of Rob Moores updateable pattern Towards Updatable https://www.toptal.com/d3-js/towards-reusable-d3-js-charts.

It is derived from Mike Bostock's Towards Reusable Charts (https://bost.ocks.org/mike/chart/) as the source of the foundational principles.

Will evolve to use 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 further charts.

MasteringD3-Resusable-ProD3js-2.2.5

This example demonstrates a reusable bar code chart that maps time-series data to vertical lines, with a button to add new data points. It builds on Mike Bostock’s reusable chart pattern and the ProD3.js module structure, using d3.scaleTime for the x-axis and d3.timeDay for date intervals. The SVG renders a white background rect and steelblue lines with stroke-opacity, while updateData triggers transitions to redraw the chart. The code uses D3 v5 with a vanilla HTML implementation, separate from any existing state management.

MasteringD3-Resusable-ProD3js-2.3B1

This example presents a reusable bar code chart built from the principles in Mike Bostock’s “Towards Reusable Charts” and the Pro D3.js pattern. It visualizes time-series data by rendering vertical line marks for each daily mention value, using d3.scaleTime to map dates to x-coordinates. The code demonstrates a modular chart factory pattern with separate functions for building scales, SVG containers, and drawing the bars, and it relies on d3.select and data joins to append the lines. Animated transitions are also included in the chart’s rendering process.

MasteringD3-Resusable-ProD3js-2.4.1

This example demonstrates a reusable, modular bar code chart built with D3.js v5, following the Pro D3.js pattern for maintainable and testable charts. It renders multiple SVG charts, each displaying hourly data distributions as radial arcs with a circular layout, using `d3.range`, `d3.map`, and angle calculations to group data by hour. The code initializes layout properties, scales, and container groups, and includes animation-ready structures, though no explicit transitions are triggered. The visualization is derived from Mike Bostock’s "Towards Reusable Charts" principles and applies a radial bar code style to show temporal patterns.

Fork of MasteringD3-Resusable-ProD3js-2.2.6

This example demonstrates a reusable barcode chart that visualizes time-series data as vertical lines, with an “Add data” button that appends new data points and animates the chart’s scale and positions using d3.transition. Built with D3 v5 and SVG, it follows the Pro D3.js pattern for modular, testable charts, deriving from Mike Bostock’s reusable chart principles. The chart renders a white background rectangle and steel-blue bars, using d3.scaleTime for the x-axis domain. The update function adds 30 days of data at three-minute intervals, triggering smooth transitions of the line positions.

MasteringD3-Resusable-ProD3js-2.3

This example demonstrates a reusable bar code chart pattern built with D3.js v5, showing a table of name, mentions, and mentions per hour alongside a time-based bar code strip. The chart updates with new data when the user clicks the "Add data" button, using the ProD3.js modular chart pattern and Rob Moore's updatable chart approach. The code defines scale functions like `d3.scaleTime()` and extracts date values with `d3.timeDay`, while rendering the table with `selectAll` and `.append` operations on SVG groups.

MasteringD3js_ReuseProD3_Ch2 pt2.2b

This example demonstrates a reusable bar-code chart pattern built with D3.js v5, displaying multiple rows of temporal data as horizontal barcode-like visualizations. Each row represents a distinct data series with randomly generated date intervals using an exponential distribution. The code implements a modular chart function that creates SVG elements within styled containers, using `d3.scaleTime()` to map date ranges to pixel positions. The example highlights the transition from D3 v3 to v5 practices, showcasing proper data binding, scale construction, and container management in a reusable component pattern.

MasteringD3-Resusable-ProD3js-2.4.3

This example demonstrates reusable, modular bar charts built with D3.js v5, following the Pro D3.js pattern and principles from Mike Bostock’s “Towards Reusable Charts.” It displays multiple charts horizontally across the page, each representing a different dataset with radial bar layouts. The code uses D3’s `d3.map`, `d3.range`, and layout functions to process hourly time-series data, while SVG groups and arc drawing handle the visual output. The visualization expands on iterative updates by cycling through datasets on an interval, showing how chart components can be dynamically refreshed.

MasteringD3-Resusable-ProD3js-2.3B

This example demonstrates a reusable bar code chart pattern for visualizing time-series data, showing daily mention counts for multiple items alongside a corresponding data table. The visualization combines an SVG-based bar code representation with an HTML table rendered through foreignObject, using D3.js v5. The code implements the ProD3.js modular chart pattern, building on Mike Bostock's "Towards Reusable Charts" principles. It uses d3.timeDay for date intervals, d3.scaleTime for temporal scaling, and d3.select with foreignObject to embed the tabular HTML content within the SVG container.
