Apr 1, 2026Monthly summary for 2026-04 focusing on feature delivery, bug fixes, impact, and skills demonstrated. This period centers on delivering a practical, user-facing tutorial to extend PyGMT’s 3-D visualization capabilities and improve onboarding for users working with 3-D surfaces. Key observations: - No major bugs reported or fixed this month. - Primary feature delivered: a Tutorial for plotting additional features on a 3-D surface using PyGMT, including steps to create a 3-D surface, add coastlines, symbols, and text annotations to enhance visualization. - Collaboration: example co-authored by Dongdong Tian for the tutorial commit, reinforcing code review and knowledge sharing. Overall impact: - Business value: enables users to visualize complex 3-D geological/topographic surfaces more effectively, accelerating analysis workflows and decision-making. - Technical achievements: end-to-end tutorial covering data preparation, visualization customization, and annotation, documented in a reusable, publishable format. - Reusability and onboarding: lowers barrier to entry for PyGMT users by providing a concrete, reproducible example. Technologies/skills demonstrated: - Python, PyGMT, 3-D plotting concepts, scientific visualization - Documentation and tutorial authoring - Collaborative development and attribution
