     ## Purpose of EduScape: Understanding Lesson Plans as a Graph
 
     EduScape helps educators visualize lesson plans as a graph, where key lesson elements (teacher, subject, grade level, learning objectives, activities, assessments, and resources) are represented as nodes with logical relationships. This structure allows teachers to better understand the connections between different parts of their lessons, facilitating clearer planning and discovery of resources.
