+        Nations over multiple decades. Each observation consists of a speech, a

+        with both countries and time.

+      <p class="text-base leading-relaxed mb-4">
+        In this project, countries are treated as nodes, while mentions from one
+        country to another form directed edges. A directed edge means that one
+        country refers to another in a speech. The direction matters, because
+        diplomatic attention is not necessarily symmetric: a country may talk
+        about another country much more than it is talked about in return.
+      </p>
+      <p class="text-base leading-relaxed mb-4">
+        Edge color reflects whether the mention is framed in a more positive or
+        negative way. This allows the network to capture both the volume and the
+        tone of diplomatic attention.

+            The graph below shows the full diplomatic mention network built from
+            the UN speeches. Each node represents a country, and each directed
+            edge represents one country mentioning another. Edge color reflects
+            whether the mention is framed in a more positive or more negative
+            way. Users can adjust the positive and negative sliders to filter
+            the graph by sentiment strength. Because the full graph contains a
+            very large number of connections, it provides a useful overview of
+            how dense and interconnected international political discourse is,
+            but it is too crowded for detailed country level interpretation.
