D3 Radial Dendrogram Only Displaying Part
I have created the code below based on Mike Bostock's example in Observable (which I know is not the same as raw d3/ javascript) https://observablehq.com/@d3/radial-dendrogram Howe
Solution 1:
Here's a quick refactor that removes the ObservableHQ craziness and moves it to a simple HTML/JavaScript page. The part you are missing is something like this:
const svg = d3
.select('svg')
.attr('width', width)
.attr('height', height)
.append('g')
.attr('transform', 'translate(' + width / 2 + ',' + height / 2 + ')');
This sizes the SVG and then moves the dendogram to the center of the SVG.
