Published at The Journal of Open Source Software 2018
Altair is a declarative statistical visualization library for Python. Statistical visualization is a constrained subset of data visualization focused on the creation of visualizations that are helpful in statistical modeling. The constrained model of statistical visualization is usually expressed in terms of a visualization grammar that specifies how input data is transformed and mapped to visual properties (position, color, size, etc.).
