\nFigure 1: From data meaning and chart intent to multiple rendering libraries.
\nFlint lets authors describe the meaning of their data and the chart they want, while a compiler determines detailed visual settings. Its hierarchical description of data semantics guides decisions that would otherwise require manual configuration. The compilation pipeline refines an intermediate representation and emits runnable specifications for Vega-Lite, ECharts, or Chart.js. The project explores this common representation as a bridge for both people and language-model agents creating charts.
