ggpointless 0.2.0

New features

New geom_fourier() and stat_fourier() fit a truncated Fourier series (via stats::fft()) to x/y data and render the reconstructed curve. Supports optional detrending ("lm" or "loess") and harmonic selection via n_harmonics (#7).
New geom_arch() and stat_arch() draw inverted catenary curves (arches) between successive points, complementing the existing geom_catenary() (#4).
New geom_area_fade() draws area charts where the fill colour fades from opaque to transparent using grid::linearGradient(). The fade target alpha is controlled via alpha_fade_to (#3).
New geom_point_glow() draws points with a radial gradient glow behind each point using grid::radialGradient(). The glow alpha, colour, and size can be customised via glow_alpha, glow_colour, and glow_size (#6).

The bundled (but outdated) datasets co2_ml, covid_vac, and female_leaders have been removed from the package. These datasets can be obtained from their
original sources: Mauna Loa CO₂, CDC vaccination data, and Wikipedia female leaders, respectively. The vignette("examples") that showcased these datasets has been removed alongside them.

The package now requires R >= 4.2.0 and ggplot2 >= 4.0.0. Several geoms take (mostly internal) advantage of new ggplot2 features such as make_constructor(), and gg_par().
Messages and errors across the package have been migrated to the cli and rlang packages, giving consistent, hyperlink-aware output.
geom_catenary() gained a vectorized chain_length argument and deprecated chainLength instead (#4).
stat_catenary() no longer wrongfully removes data points when the upper limit in ylim() is set to the maximum y-value of the dataset (#1).

New geom_catenary() and stat_catenary() let you draw a hanging chain.
geom_lexis() supports linewidth argument now, which was released in ggplot2 v3.4.0.
geom_lexis() deprecates point_size argument in favour of size.

New geom_chaikin() and stat_chaikin() apply Chaikin’s corner cutting algorithm to ragged paths.
