Visualizations are a critical part of mathematics practice and education, and computers and open-source web technologies provide accessible ways to create high-quality mathematics visualizations at virtually no cost. However libraries and languages to create visualizations for mathematics are typically fine-grained, low-level, and targeted to vector graphics domain experts or web developers, not mathematics students or teachers or end-users. We present demos of a functional domain-specific language interface to the JSXGraph visualization library embedded in F# that emphasizes readability, composability, and the ability of end-users to easily create and manipulate elements of high-quality interactive mathematics visualizations without needing vector graphics or web development domain knowledge.
