rollupData = d3.rollups(powerplants_2019, v => d3.sum(v, d => toNum(d["Plant annual net generation (MWh)"])), d => d["Plant state abbreviation"], d => d["Plant primary fuel generation category"]);
import {layoutChildren} from "@emfielduva/dvlib_layout"
dataLayout = layoutChildren("powerplants", rollupData)
and then we draw
using the dvClusterDendogram convenience function from my library.
format: dvClusterDendogram(elem,data,sizeX,sizeY,scaleR)
denElem = d3.select(svgContainer).select("#layer1")
dendo = dvClusterDendogram(denElem,dataLayout,3500,800,0.005)
Purpose-built for displays of data
Observable is your go-to platform for exploring data and creating expressive data visualizations. Use reactive JavaScript notebooks for prototyping and a collaborative canvas for visual data exploration and dashboard creation.
