Open the Debug Pie Chart with `Shift + F3` on Java Edition
Use the pie chart to inspect world generation and chunk data
Look for sections related to structures, loot, or chest-containing features
Move around the area and watch for spikes in structure-related slices
Search near generated structures such as dungeons, mineshafts, temples, bastions, or strongholds
Use the pie chart to identify when a structure chunk is loaded
Explore the structure area manually after locating the likely chunk
Check underground and hidden rooms where chests commonly generate
Repeat in different chunks until chest-generating structures appear
