Create a scientific infographic with a structured framework style. Use beige background, thick black rounded borders, dashed inner lines, and pastel panels (light tan, green, blue, gray). Title: "Data Pipeline for DWTS Score–Vote Analysis". Three horizontal tiers with large downward arrows:Data Cleaning: Convert weekX_judgeY_score to numeric, treat NaN, parse elimination week with regex, set post-elimination zeros as missing.Data Aggregation: Aggregate by season-contestant-week into weekly_df, remove missing scores, define active vs eliminated; aggregate to seasonal_df.Feature Engineering & Augmentation: Add weekly features (age, US-born, cumulative weeks); external validation with Wikimedia Pageviews API for log views and momentum.Modeling: Fan vote prediction with regression/classification models; evaluation metrics (RMSE, ranking consistency, robustness).Ensure vector-like design, clear typography, minimal decoration, and no watermarks.
