The dataset is available at: <${gist}> See the [\`README.md\`](${gist}) file for details on how this data was gathered. See the [Java 11 API Hierarchy - Data Wrangling](https://observablehq.com/@sjengle/java-11-api-hierarchy-data-wrangling) notebook for how to convert this data into a hierarchical format. This specific notebook illustrates visualize the data using the [d3-hierarchy](https://github.com/d3/d3-hierarchy) layouts. We will focus just on the different layouts in this notebook, and not interactivity or labeling. See the [d3-hierarchy collection](https://observablehq.com/collection/@d3/d3-hierarchy) for notebooks including more robust labeling of nodes and different forms of interactivity. *These examples are based off an older [bl.ocks.org](https://bl.ocks.org/-/about) demo for [visualizing the Java 8 API hierarchy](http://bl.ocks.org/sjengle/cdda19c7942c2ff569161ee0566e1396) using D3 version 4.* `33:T67f,function showTooltip(g, node) { let gbox = g.node().getBBox();
