Chart Type for Process Mining. Keywords: process, mining, variants, path, bottleneck, log, event. Best Chart: Process Map / Graph. Secondary Options: Directed Acyclic Graph (DAG), Petri Net. When to Use: Analyzing event logs to visualize actual process flows; identifying bottlenecks and deviations in ops/product funnels. When NOT to Use: No event log data available; audience expects a static flowchart (use diagram tool); node count > 100 without pre-filtering. Data Volume Threshold: <30 nodes: SVG; 30–100: Canvas; >100: apply variant filtering (top 80% of cases) before rendering. Color Guidance: Happy path: #10B981 thick line. Deviations: #F59E0B thin line. Bottleneck nodes: #EF4444 fill. Accessibility: B — Complex graphs are hard to navigate. Provide path summary text. Highlight top 3 bottlenecks as annotations.. A11y Fallback: Path summary table (variant → frequency → avg duration); top 3 bottlenecks as text annotation panel. Library: React-Flow, Cytoscape.js, Recharts. Interactive Level: Drag + Node-Click.
