{"version":"1.0","type":"rich","title":"Call Graph","description":"A force-directed call graph visualizes communication patterns among seven “flex” microservices, with circles representing system nodes and arrows showing directed edges. Node positions update dynamically via `d3.forceSimulation`, combining `forceLink`, `forceManyBody`, and `forceCenter`. Dragging nodes with the `d3.drag` API repositions them and restarts the simulation. The SVG renders labeled circles and arrowheads defined by a marker, with data from the `system_nodes` metadata.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/62780725f8934acfaafc5d93ce1a6f5b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
