+## center
+
+Takes a [Feature][1] or [FeatureCollection][2] and returns the absolute center point of all features.
+
+**Parameters**
+
+-   `geojson` **[GeoJSON][3]** GeoJSON to be centered
+-   `options` **[Object][4]** Optional parameters (optional, default `{}`)
+    -   `options.properties` **[Object][4]** Translate GeoJSON Properties to Point (optional, default `{}`)
+    -   `options.bbox` **[Object][4]** Translate GeoJSON BBox to Point (optional, default `{}`)
+    -   `options.id` **[Object][4]** Translate GeoJSON Id to Point (optional, default `{}`)
+
+**Examples**
+
+```javascript
+var features = turf.points([
+  [-97.522259, 35.4691],
+  [-97.502754, 35.463455],
+  [-97.508269, 35.463245]
+]);
+
+var center = turf.center(features);
+
+//addToMap
+var addToMap = [features, center]
+center.properties['marker-size'] = 'large';
+center.properties['marker-color'] = '#000';
+```
+
+Returns **[Feature][5]&lt;[Point][6]>** a Point feature at the absolute center point of all input features
