What the trend data tells us
The English title describes the topic of the source listing. Its appearance in a ranking measures attention within that platform; the ranking alone does not explain the cause of a spike or verify the underlying claim.
This stable URL remains available after a topic leaves a live ranking. Observation span is elapsed time between sightings, not continuous time on a chart. Platforms use different ranking and heat systems; their metrics are not added together.
