This example visualizes the structure of an Android build failure by mapping the dependency graph that leads to a `DexArchiveMergerException`. It uses a force-directed layout with `d3.forceSimulation` to position nodes representing Gradle tasks and external libraries, while `d3.geoPath` draws curved links between them. The code renders the graph to a Canvas element, retrieving pixel data via `getImageData` to highlight overlapping nodes. Data is hardcoded from the stack trace in `faq_04.java`, showing the dex-merging step where duplicate classes cause the merge conflict.
