Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
PyDexter abstracts away many D3.js features, limiting fine-grained control over chart elements.
Rendering complex charts with thousands of data points can lead to slow performance and browser hangs.
The project has a small number of contributors, leading to slower issue resolution and fewer external integrations.
v0.1 to v0.2 migration required rewriting chain definitions, causing substantial refactoring effort for existing users.
