A brushed time-series chart filters the main visualization, updating a least-squares regression trendline and its equation. The main chart renders blue and orange lines for well measurements with a bar chart for rainfall, using d3.brushX, d3.nest, and d3.scaleTime. Data loads from CSV files, with SVG rendering and a categorical color legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/19e8e0118e774578b4d7044ff4c6cdcd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
