Screenshot from 2024-03-15 16-41-32 i know blue line is my slam path but how about the yellow and the red lines mean?

Yellow is proximity detection (or local loop closure detection), red is global loop closure detection. If you right-click on the view, there is a menu option showing the different link colors (that can be changed). To know more about those links, see section 3.4 of this paper: RTAB-Map as an Open-Source Lidar and Visual SLAM Library for Large-Scale and Long-Term Online Operation.
