This example demonstrates a reusable and updateable bar chart built with D3.js v5, following the patterns from Mike Bostock’s "Towards Reusable Charts" and Rob Moore’s "Towards Updatable" approach. It renders SVG rectangles scaled from an array of numerical data, with smooth transitions for updating bar dimensions, colors, and datasets. The chart exposes getter-setter methods for `width`, `height`, `fillColor`, and `data` that trigger animated updates via `transition().duration()`. New bars fade in while exiting bars shrink and fade out, all rendered in a vanilla HTML page with multiple chart containers.

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.

Towards_Updateable-Resusable-ProD3js_d3jsCharts-UpdateDataOnly

This example demonstrates an updatable bar chart pattern in D3.js v5, derived from Mike Bostock's reusable chart principles and Rob Moore's updateable pattern. The chart renders with SVG, showing horizontal bars whose lengths are proportional to data values, with spacing, height, and scale computed from the data array. The code uses `d3.select`, `d3.max` for domain scaling, and the `.data()`, `.enter()`, and `.append('rect')` methods to build bar elements dynamically. A separate container structure is prepared for axes and title, though current axes remain commented out.

Towards_Updateable-Resusable_d3jsCharts

A reusable bar chart demonstrates the updateable pattern, showing how dynamically changing data, dimensions, and fill colors animate smoothly with D3 transitions. Three chart instances render on the page, each driven by the same `barChart()` factory function loosely based on Mike Bostock's reusable chart pattern. The chart uses `selection.each`, `data`, `enter`, `exit`, and chained `transition` calls to handle updates, including staggered opacity and width changes for new bars, while removed bars shrink and fade out. The standalone HTML file is built with D3 v5 and SVG for rendering.

Towards_Updateable-Resusable-ProD3js_d3jsCharts-Update with Join(j

This example demonstrates a reusable, updateable bar chart built with D3.js v5, following Rob Moore's update pattern and the ProD3.js architecture. It renders sales data as horizontal bars in SVG, with each bar’s width proportional to its value, and includes a title and axis placeholders. The chart uses `d3.select` and `.join('rect')` to handle enter and update states, while scales and axes are defined via `d3.scaleBand` and `d3.axisBottom`/`d3.axisLeft`. The code is structured as a module with configurable attributes like `fillColour` and `barPadding`, and it displays data from an array of objects containing `salesperson` and `sales` values.

MasteringD3-Resusable-ProD3js-2.2.4

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.

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-2.4.1

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.

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.

d3Edge_v5ProReusable_BarChart-Ch4.1

This example demonstrates a reusable bar chart built with D3.js v5, following the Pro D3.js pattern for modular chart creation. The SVG-based visualization renders two separate bar charts from hardcoded arrays of numeric string values, with steel-blue bars and no axes. The chart employs a dispatcher object to broadcast a customHover event, which prints data values and indices to the console when the mouse hovers over a bar. The implementation uses D3’s `scaleBand` and `scaleLinear` for positioning and scaling, while the reusable `barChart` module exposes configurable width and height accessors.
