Using Case Canvas's heatmap view to see where I was actually thin
Had used Case Canvas's graph view already (posted about that separately), but the heatmap view specifically gave me a different, useful angle — a quick visual sense of relative evidence density across criteria that the node-and-line graph didn't make quite as immediately obvious. Seeing it as a heatmap rather than a graph made the unevenness in my evidence base visually unmissable in a way that was harder to fully register looking at individual nodes and connections one at a time. Two criteria that I'd been treating as "roughly similar strength" in my head turned out to look very different once represented this way — one was genuinely dense, the other noticeably sparse, and the visual made that gap impossible to keep ignoring. If you've used the graph view but not the heatmap, or vice versa, I'd recommend both — they surfaced slightly different things for me, and seeing the same underlying evidence represented two different ways caught things a single view alone might have let me keep overlooking.
