Topic mix over time
A year-by-year stacked chart of topic composition - how the conversation's subject mix shifted across the eras.
Each row is a year; each segment is that year's share of threads assigned to a topic category. A thread carrying more than one topic is counted once per topic it carries, so rows can sum to more than the year's thread total.
