Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
LightGraphs is exclusively designed for the Julia programming language, limiting its use to developers proficient in or willing to learn Julia.
Julia's package manager (Pkg) can be complex for new users, especially when dealing with version-specific dependencies required by LightGraphs.
While generally high-performing, some specific graph algorithms may not scale optimally for extremely large graphs or complex operations.
