I’ve put the first interactive charts from my crude benchmark comparison on the site. You can compare grades by API gravity and sulfur, inspect individual points and look at their regional context.
I wanted to make the comparison easy to explore while keeping the source differences visible.
For this pass I pulled the analysis into three views:
- an ECharts scatter for quick inspection of the API/sulfur relationship
- a Plotly scatter for fuller hover detail and benchmark-comparable filtering
- a Folium regional map for API gravity context
The comparison I care about
API gravity and sulfur give me a useful starting point for comparing crude grades. Light/sweet and heavier/sourer grades have different refining implications, and the scatter lets you see how the benchmark records line up on those two measures. Other quality properties still matter.
I pay particular attention to which records belong in the same comparison. Some grade records are repeated, partial or drawn from different sources. For the benchmark-comparable view, I select one canonical row per grade and prioritize records by source tier. That gives the WTI vs Brent slice an explicit selection rule.

Notes from this pass
I kept the ECharts and Plotly views similar so I can spot disagreements between the exports. The Folium map adds regional context: if a group of grades catches your attention in the scatter, you can explore where those grades come from.
The WTI vs Brent comparison CSV sits alongside the visuals, so you can inspect the records behind the comparison and its selection rule.
What I am checking next
Next I want to explain the outliers more clearly and make the benchmark-source assumptions easier to inspect from the project page. The charts give you a way into the data; those notes will help explain the points that need more context.
