Economic Time Series

Time trends

Line charts for showing how a quantity changes over time. Six variants from generic to survey-flavored: a simple (year, value) series with optional confidence intervals, the GSS demographic-split chart with presidential-term reference areas, an indexed mode that rebases every series to 100 at a baseline year, a metadata-panel layout, a small-multiples grid, and an Observable Plot rendering.

Demographic breakdowns

Three chart shapes (line, bar, dot) for showing one outcome across five demographic axes — Age, Education, Income, Race, Gender — from a single dataset shape. Includes the multi-panel composite for showing the same outcome on all five axes side-by-side with consistent scales.

Distributions

The distribution family: histogram, violin, KDE density (single / overlay / combined), and split bar. Use a histogram when bin counts matter, a density plot when the shape matters, a violin when you want both shape and summary, and a split bar to highlight a subgroup difference within each category.

Scatter + regression

Scatterplots with OLS regression line, 95% confidence band, and R² display. Four flavors: a generic Recharts version built for European Social Survey data, plus three Observable Plot variants tuned for health-survey two-variable plots (basic, faceted by a third variable, regression overlay).
