I visualized 7 years of Brent crude oil futures using year-based color encoding — the market regimes cluster in a way a single-color line never would. # Analysis of Brent Crude Futures Data Visualization Built this in matplotlib using 1.89 million rows of 1-minute Brent crude futures data (2019–2026), resampled to daily closes. A few deliberate design decisions worth discussing. # Color Encoding The central choice was year-based color encoding rather than a single continuous line.
