Build a Revenue and Stock Price Combo Chart with Python

Source: Dev.to

Financial charts often combine metrics that live on completely different scales. For example: I wanted to recreate the infographic style seen on Visual Capitalist using pure Python and SVG. The chart combines: annual revenue as bars, One of the most interesting parts is the clipping effect. The stock-price area spans the entire chart, but SVG clipping reveals it only inside the revenue bars: stock_layer = dp.G().append( dp.Path( d=area_generator(stock_points), fill=“url(#area-gradient)”, clip_path=“url(#revenue-clip)”, ) )

This creates a visual connection between the two datasets without sacrificing readability. The chart is generated entirely as SVG using pyDreamplet, which means: resolution independent output, A few design decisions helped keep the chart readable: bars and lines use different visual encodings, The complete tutorial walks through: loading the data, 👉 Full step-by-step tutorial: https://py.dreamplet.com/tutorials/combo-chart 👉 Source code: https://github.com/marepilc/pydreamplet-showcase/tree/master/scripts/combo_chart
