+The Graphviz and vis.js visualizers render data that matches the `Graph` interface.

 ## UI Features
 
--   Multiline Expressions: Press `shift+enter` to add a new line, ctrl+enter to evaluate the expression.
-    Subsequent new lines can be inserted with a single `enter`.
+-   **Multi-line Expressions**: Press `shift+enter` to add a new line and `ctrl+enter` to evaluate the expression.
+    When only having a single line, `enter` submits the current expression,
+    but when having multiple lines, `enter` inserts another line break.
