Slice of Reality
Data slicers are very useful and cool to look at, but they can misrepresent reality. Looking at data in isolation helps to narrow things down, but sometimes looking to narrowly limits seeing reality.
Unfortunately, data in isolation is just that. Data without context is data without all that much meaning.
But adding anecdotal information to data doesn’t necessarily scale that well. Without context, it is very hard to figure out the why.
You will find patterns and patterns can be telling, but they are not always enough. Patterns are informative, but things don't always follow the pattern.
