+review:
+  strengths:
+  - Mathematically correct Smith chart implementation with proper constant-r circles
+    and constant-x arcs
+  - Excellent realistic RF engineering data scenario with antenna resonance model
+  - Clean visual hierarchy with yellow locus standing out against blue/gray grid
+  - 'Good use of Bokeh features: ColumnDataSource, Label annotations, both PNG and
+    HTML export'
+  - Proper normalization and gamma conversion mathematics
+  - Well-positioned frequency labels with offset to avoid overlap with data points
+  weaknesses:
+  - Could add HoverTool for interactive impedance/frequency inspection in the HTML
+    version
+  - Grid r/x labels are slightly small compared to other text elements
+  - Axis labels could include dimensionless clarification
+  image_description: The plot shows a Smith chart with the classic circular impedance
+    coordinate system. A blue outer boundary represents the unit circle (|Γ| = 1).
+    Gray constant resistance circles (r = 0.2, 0.5, 1, 2) are visible emanating from
+    the right side, and gray constant reactance arcs curve symmetrically above and
+    below the horizontal axis. A yellow impedance locus curve with circular markers
+    traces a frequency sweep from 1.0 GHz to 6.0 GHz, forming a characteristic loop
+    pattern in the right half of the chart. Frequency labels (1.0 GHz, 2.2 GHz, 3.6
+    GHz, 4.8 GHz, 6.0 GHz) are placed at key points along the locus in blue text.
+    A dark blue marker at the center marks the matched condition (Z=Z₀). Small gray
+    labels indicate r-values (r=0.2, r=0.5, r=1, r=2) along the horizontal axis and
+    x-values (x=0.5, x=1, x=2) on the boundary arcs. The title "smith-chart-basic
+    · bokeh · pyplots.ai" appears at top-left. Axes are labeled "Real(Γ)" and "Imag(Γ)".
+    The background is light gray (#fafafa).
