• Created on Monday, October 26, 2026
• Built with R Markdown (ioslides_presentation) and Plotly
• Data: R’s built-in volcano dataset — a topographic grid of Maunga Whau (Mt Eden), a dormant volcano in Auckland, New Zealand
• 87 × 61 grid of elevation readings, 10 m apart

Tip: every plot is interactive — drag to rotate, scroll to zoom, hover for values.

Click legend entries to show or hide each slice.

• The summit reaches 195 m; the lowest point on the grid is 94 m
• The cross-sections reveal the crater dip near the peak
• Plotly turns a static matrix into something you can explore from every angle

Thank you!
