{"en":"Vellum is a low-level graphics framework for R that resolves text measurement, layout, and mark positions before anything reaches a canvas. Powered by a Rust backend, it enables developers to inspect scene geometry, wrap text dynamically, repel colliding labels, and lint figures prior to output.\n\nOperating at the level of R's grid system, Vellum supports modern paint models including gradients, patterns, masks, and density rasterization for large datasets. A single solved scene can be rendered consistently across raster and vector formats.","zh":"Vellum 是一个面向 R 语言的低级图形框架，其核心在于在任何图形到达画布前，就完成文本测量、布局求解和元素坐标计算。通过底层的 Rust 渲染库，它允许开发者对场景进行结构化查询、文本自动换行与缩放、标签碰撞消除以及渲染前的静态检查。\n\n该框架与 R 原生的 grid 系统处于同一层级，支持图层混合、渐变、图案填充、遮罩以及大数据点的网格聚合渲染（datashade）。开发者可以通过统一的场景对象输出多种格式，保持不同后端间几何结构的一致性。"}
