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.

Transition

The visualization demonstrates a multi-stage transition of fruit count data, first morphing circular bubbles into rectangular bars, then into a pie chart. It uses D3.js version 3.5.6 with SVG and animation via chained `transition()` calls, employing `d3.scale.ordinal` and `d3.scale.linear` for positioning. The data comes from `fruit.csv` with fruit names and counts. After five seconds, a `setTimeout` triggers a second transition where bars become pie slices using `d3.layout.pie` and `d3.svg.arc`, with y-axis removal and element replacement.

Fork of D3 Update Pattern –Punchcard Example V5

This interactive punchcard chart uses D3 v5 to visualize barley crop yields across multiple Minnesota sites over two years. Users select a site from a dropdown menu, triggering animated transitions of circles positioned by year and barley genotype, with circle radius scaled by yield value. The chart displays SVG axes and marks, and the code uses D3's `nest()`, `map()`, `dispatch`, `scalePoint`, `scaleSqrt`, and `axisBottom` for data aggregation and rendering.

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 Line Chart

This chart visualizes barley yield data across multiple varieties and experimental sites for the years 1931 and 1932. Each line represents a variety, with the x-axis mapping the six locations and the y-axis representing yield. The line chart is rendered using SVG within a D3 v4 framework, sourced from a TSV file containing yield measurements across 10 barley varieties at 6 sites over 2 years. The visualization uses a multi-line layout to show how each variety's yield varies across locations, with the data parsed and plotted from the tab-separated values in barley.tsv. The lines are drawn without fill, keeping the chart clean and focused on the trend comparisons between varieties across sites.

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()`.

Transition D3 Scatter plot

This example demonstrates an animated scatter plot of the Iris dataset, cycling through different numerical columns as the x-axis variable every three seconds. Each transition smoothly moves the existing SVG circles to their new positions over two seconds, with the axes updating accordingly. The visualization uses D3.js v7 with the `transition()` API to animate circle positions and axis scales, while the React framework handles the component structure. Data is loaded via `d3.csv` from a remote GitHub gist.

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)`.
