+
+            <h3>Context & Question</h3>
+            <p>
+                This example demonstrates how to use external visualization libraries
+                like R's ggplot2. You can create visualizations in your preferred
+                tool/language, export them as images, and include them in your portfolio.
+            </p>
+
+            <h3>Design Decisions</h3>
+            <p>
+                This visualization was created using R and the ggplot2 library,
+                a powerful tool for creating publication-quality graphics. The code
+                loads city population data and creates a line chart showing population
+                trends over time for different cities. After creating the visualization
+                in R, it was exported as a PNG image and included in the portfolio.
