Visualization

Visualisation is explicit and backend-specific. Use fincore.viz.get_backend when plotting a domain result, or use report renderers for document output.

from fincore.viz import get_backend

backend = get_backend("matplotlib")
figure = backend.plot_returns(cumulative_returns)

Install fincore[visualization] for matplotlib, seaborn, Plotly, and Bokeh; install fincore[interactive] when only Plotly/Bokeh is required. Backends receive already-computed data and do not own financial calculation semantics.
