+\usage{
+pmPaintRule(
+  dataLayer,
+  symbolizer,
+  minzoom = NULL,
+  maxzoom = NULL,
+  filter = NULL
+)
+}
+\arguments{
+\item{dataLayer}{Character. The name of the data layer in the vector
+tile source (e.g., "water", "earth", "roads").}
+
+\item{symbolizer}{A symbolizer object created with one of the symbolizer
+functions (e.g., \code{\link{pmPolygonSymbolizer}},
+\code{\link{pmLineSymbolizer}}).}
+
+\item{minzoom}{Numeric. Minimum zoom level at which this rule applies.
+Default is NULL (applies at all zoom levels).}
+
+\item{maxzoom}{Numeric. Maximum zoom level at which this rule applies.
+Default is NULL (applies at all zoom levels).}
+
+\item{filter}{Character. A JavaScript expression string that filters
+features. The expression has access to \code{zoom} and \code{feature}
+variables. Default is NULL (no filter).}
+}
+\value{
+A list representing the paint rule configuration.
+}
+\description{
+Creates a paint rule that specifies how to render features from a
+particular data layer. Paint rules control the visual appearance of
+polygon, line, and point features.
+}
+\examples{
+# Render water polygons in blue
+pmPaintRule("water", pmPolygonSymbolizer(fill = "steelblue"))
+
+# Render roads with zoom-dependent visibility
+pmPaintRule("roads", pmLineSymbolizer(color = "gray", width = 2),
+            minzoom = 10)
+
+# Filter to only show highways
+pmPaintRule("roads",
+            pmLineSymbolizer(color = "orange", width = 4),
+            filter = "feature.props.kind === 'highway'")
