+TALA 0.3.0 implements position-locking to give control over parts of the diagram where you need it. This is an advanced feature that opens up a world of possibilities to create small bubbles of customized layouts and combine it with autolayout. For example, here's a legend:
+
+<img src="https://raw.githubusercontent.com/terrastruct/TALA/master/docs/assets/legend.png" />
+
+```d2
+Legend: {
+  top: 0
+  left: 0
+  blue: "" {
+    width: 20
+    height: 20
+    left: 0
+    top: 0
+    style.stroke: black
+  }
+  blue-explanation: Actions {
+    shape: text
+    left: 50
+    top: 0
+  }
+
+  green: "" {
+    width: 20
+    height: 20
+    left: 0
+    top: 50
+    style.fill: honeydew
+    style.stroke: black
+  }
+  green-explanation: Intermediate artifacts {
+    shape: text
+    left: 50
+    top: 50
+  }
+}
+```
+
+We're excited to see all the creative diagrams this enables!
