This static punchcard chart visualizes barley yields across multiple sites and years using a reusable D3.js v5 module. It displays data points as circles positioned by year on the x-axis and site on the y-axis, with circle radius encoding yield values. The chart implements the general update pattern derived from Mike Bostock’s reusable charts approach, adapted with the ProD3 pattern. It uses d3.scalePoint, d3.scaleLinear, d3.scaleSqrt, and d3.schemeAccent to render the SVG elements.

Punch card Chart: v5 Static Reusable

A vanilla HTML implementation of Chris Henrick PunchCard tutorial "D3JS v4 General Update Pattern: Punchcard Chart"

https://clhenrick.io/d3-v4-general-update-pattern-punchcard-chart/

bl.ock: https://bl.ocks.org/clhenrick/2b6b5360748a06b26bfd50d96998b741

The pattern 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.

Reusable Barley PunchCard Chart v5 - static

This example presents a static punchcard-style chart visualizing barley yield data across multiple years and experimental sites. The visualization displays data points as circles arranged in a grid, with each cell representing a specific variety and location combination. Built with D3.js v5, the implementation demonstrates a reusable chart module pattern based on principles from Mike Bostock’s reusable charts and the Pro D3.js book. The code uses d3.scaleOrdinal for color encoding, d3.axisBottom and d3.axisLeft for axes, and SVG rendering with the data loaded from a CSV file containing 160 yield measurements with attributes for genotype, year, and site.

Reusable Barley (Block) PunchCard Chart v5 - dynamic

A dynamic punch card chart displays barley yield data across multiple growing sites and years. The visualization uses a reusable D3 module following the ProD3 pattern, with circle size scaled by yield value using `d3.scaleSqrt` and color encoded by a `d3.scaleOrdinal` scheme. Users can interact with the chart, which redraws circles and axes dynamically. The implementation relies on D3 v5 APIs including `d3.axisBottom`, `d3.axisLeft`, and `d3.scalePoint`, rendering to SVG within a container group structure.

Reusable Barley PunchCard Chart v5 - static

This punch card chart visualizes barley yield data from 1927-1929 across multiple sites and barley genotypes. The chart uses a static SVG rendering with a reusable D3.js v5 module pattern, featuring circular marks whose radius encodes yield magnitude and color distinguishes barley genotypes. The visualization incorporates D3's `scalePoint` for the categorical y-axis, `scaleLinear` for the year-based x-axis, and `scaleSqrt` for radius scaling, alongside ordinal color mapping. The data is sourced from a CSV file containing yield measurements for different barley varieties across experimental stations in Minnesota.

Barley PunchCard Chart v4 - static

A static punchcard chart visualizes barley yield data across six sites and multiple genetic varieties, with a selected site displayed as a grid of circles representing each variety's yield per year. The D3.js v4 code uses `d3.nest()` to group the `barleyfull.csv` dataset, `d3.scalePoint()` for the categorical y-axis, `d3.scaleLinear()` for the year axis, and `d3.scaleSqrt()` for circle radius. The visualization is rendered as an SVG, employing the general update pattern with `selectAll`, `enter`, and `append` to draw circles, while axes are generated via `d3.axisLeft()` and `d3.axisBottom()`.

Barley PunchCard Chart v5 - static

This example shows barley yield data for a single site, with each variety as a horizontal row of circles positioned by year, where circle radius encodes yield and color distinguishes barley genotypes. The chart is built with D3 v5 using nested data from a CSV file, rendered as SVG. It employs `d3.nest()` for grouping, `d3.scalePoint` for the y-axis, `d3.scaleLinear` for years, and `d3.scaleOrdinal` with the `schemeAccent` color palette, alongside `d3.axisLeft` and `d3.axisBottom` for axes.

Fork of Barley PunchCard Square Chart v5 - static

This visualization presents yield data from the classic barley dataset as a static punch-card chart. It displays a single site, Crookston, with barley varieties along the vertical axis and years on the horizontal axis, using square rectangles sized by yield value. The code uses D3 v5’s `d3.nest()` to group data hierarchically, `d3.scalePoint()`, `d3.scaleLinear()`, and `d3.scaleSqrt()` for positioning and sizing, and `d3.axisLeft()`/`d3.axisBottom()` for axes. SVG rectangles are colored via `d3.scaleOrdinal(d3.schemeAccent)`.

D3 Update Pattern –Punchcard Example

A punchcard chart displays barley yield data across six sites, with each row representing a barley genotype and each column a year. Users select a site from a dropdown menu to trigger a smooth, 750-millisecond transition that updates the chart via the D3.js **v4** general update pattern. The visualization uses **d3.scalePoint** for axes, **d3.scaleSqrt** for circle radii, **d3.scaleOrdinal** with **d3.schemeCategory20b** for colors, and **d3.axisLeft**/ **d3.axisBottom** for rendering. Data from `barleyfull.csv` is loaded using **d3.csv** and processed with **d3.nest** and **d3.map**, with events handled via **d3.dispatch**.

D3 Update Pattern – (block)Punchcard Example V5

This interactive punchcard chart visualizes barley yield data across multiple sites and years, with each circle’s size mapped to the yield value. A dropdown menu filters the dataset by site, and when a new site is selected, the chart transitions smoothly. The visualization uses D3 v5’s `dispatch` event system, `d3.nest()`, and `d3.map()`, along with `d3.scaleSqrt()` for circle scaling and `transition().duration(750)` for animated updates. The data is loaded from a CSV file, and the chart is rendered as SVG with ordinal axes.
