This systematic literature review analyzes 90 high-quality papers selected from an initial pool of 288 to identify applications, effectiveness, and research gaps in visualization tools for computing education. We categorize tools across domains such as algorithms, programming, online learning, and problem-solving, highlighting their impact on student engagement and learning outcomes. However, we find a lack of rigorous evaluations and a need for specialized visualization models to address specific challenges. Our findings offer actionable insights for educators and researchers to improve teaching methodologies through visual strategies.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing → Visualization systems and toolsHuman centered computing computing → Visualization systems and tools10.2312/eved.202510279 pages
