LION: Fast and High-Resolution Network Kernel Density Visualization
Summary: LION accelerates network kernel density visualization on large spatial datasets, explicitly exploiting output resolution to reduce worst-case generation time without added space. Experiments show 2.86–35.36× speedups over ADA at high resolutions. (summarized by gpt-5.6-luna on Jul 24 2026)
