Abstract—This paper is intended to develop an algorithm visualization, particularly Bresenham's Line Algorithm for a Computer Graphics course. Algorithm visualization technology graphically illustrates how algorithms work. This visualization can be used to explain how a line is produced in a display computer for education. This research consists of 6 steps which are concept, design, obtaining of content material, assembly, testing, and distribution. During the testing step, the application is run and checked to confirm that it performs exactly what the author has intended and the students can learn Bresenham's Line Algorithm by studying the visualization. Flash movie demonstrate how Bresenham's Line Algorithm visualized by inputing data, performing calculation, and then returning the calculated results back to output text field. Subjects of the research were students of Department of Informatics Universitas Persada Indonesia YAI for implementation of the learning. The data were analyzed using the analytic descriptive method and interpreted in a narrative way based on the research findings. The visualization and the interactivity have been well tested by the students, and the results indicate that students increase their ability to program graphic application.
