+## Usage
+
+```javascript
+var symbols2aliases = require( '@stdlib/plot/base/symbols2aliases' );
+```
+
+#### symbols2aliases( symbols )
+
+Converts an array of symbol [aliases][@stdlib/plot/base/symbol-aliases] and/or [shorthands][@stdlib/plot/base/symbol-shorthands] to canonical [symbol aliases][@stdlib/plot/base/symbol-aliases].
+
+```javascript
+var out = symbols2aliases( [ 'o', 's' ] );
+// returns [ 'circle', 'square' ]
+```
+
+If unable to resolve an alias for an element of the input array, the corresponding element in the output array is `null`.
+
+```javascript
+var out = symbols2aliases( [ 'o', 'beep' ] );
+// returns [ 'circle', null ]
