 review:
   strengths:
-  - Excellent implementation of gradient fill from specification notes (alpha 0.3-0.5)
-  - Proper title format exactly matching the required pattern
-  - Clean, readable code following KISS principles with proper seed for reproducibility
-  - Good use of weekly cyclical pattern in data making the visualization interesting
-  - Proper container-based screenshot approach for accurate chart dimensions
+  - Gradient fill implementation using Highcharts linearGradient is well done, creating
+    a visually appealing transition from opaque to transparent
+  - Realistic data generation with growth trend + weekly cyclical pattern + noise
+    creates a convincing website traffic dataset
+  - Proper Selenium-based export pipeline following library best practices (inline
+    JS, headless Chrome)
+  - Good font sizing for the 4800x2700 canvas (72px title, 48px axis titles, 36px
+    labels)
+  - Clean, well-structured code following KISS principles
   weaknesses:
-  - Y-axis starts at 0 creating large empty space below the data (could use min property)
-  - Axis labels lack units (could be "Daily Visitors (count)" or "Day of Month (date)")
-  - Could leverage more Highcharts-specific features like hover tooltips or animation
-  image_description: The plot displays a basic area chart showing website traffic
-    over 30 days. The chart has a blue color scheme (#306998) with a gradient fill
-    that transitions from semi-opaque at the top (~0.5 alpha) to nearly transparent
-    at the bottom (~0.1 alpha). The title "area-basic · highcharts · pyplots.ai" is
-    prominently displayed at the top in bold. The X-axis is labeled "Day of Month"
-    with values from 1-30, and the Y-axis shows "Daily Visitors" ranging from 0 to
-    4000. Small blue circular markers are placed at each data point along the line.
-    The data shows a clear upward trend with weekly cyclical patterns (peaks roughly
-    every 7 days). Grid lines are subtle and visible on both axes. The overall layout
-    is clean with white background.
+  - Y-axis minimum set to 1000 creates excessive wasted vertical space — data starts
+    around 1900, so nearly 1/3 of the vertical axis shows empty area, compressing
+    the actual data visualization
+  - X-axis title Day of Month is not rendering or is cut off in the final PNG output,
+    despite being configured in the code
+  - The plot.html standalone file is generated unnecessarily (not required by spec)
+  image_description: The plot displays a basic area chart titled "area-basic · highcharts
+    · pyplots.ai" centered at the top in bold text. The chart shows daily website
+    visitors (count) over 30 days. The line is drawn in a steel-blue color (#306998)
+    with small circular markers at each data point. The area beneath the line is filled
+    with a vertical linear gradient, transitioning from semi-transparent blue near
+    the line to nearly transparent blue at the bottom. The Y-axis is labeled "Daily
+    Visitors (count)" and ranges from 1,000 to 3,900. The X-axis shows day numbers
+    1 through 30, but the "Day of Month" axis title is not visible in the rendered
+    image (likely cut off or not rendered). The data shows an upward growth trend
+    from ~2,400 to ~3,700 visitors with clear weekly oscillations. Gridlines are present
+    and subtle. There is significant wasted vertical space between Y=1,000 and Y≈1,900
+    where no data exists, reducing the effective visual resolution of the actual data
+    range.
