For those of us (hand up!) who are visual learners, MooseRoots' visuals are a great help in understanding the contextual information that tells the story of an ancestor's life. Dates and lineage are vital, of course, but to get a feel for what an ancestor's life was like in the day-to-day reality, contextual information is what fills in the gaps.
What was happening in the government during that time? In popular culture? What was the median income for that city? This type of information is helpful in "getting to know" an ancestor -- and seeing it depicted in graphics is a fun and useful plus.
