ggsurveillance 0.4.0 (2025-05-09)

geom_bar_diverging() for diverging bar charts, including:
- stat_diverging() for easy labeling of these charts
- scale_x_continuous_diverging(): Creates symmetric diverging scales
- geom_area_diverging() for continuous variables.
- geom_col_range(): The underlying geom which creates bars from x, ymin and ymax (or flipped).
geom_label_last_value() for labeling of the last value of a time series (like geom_line())
- stat_last_value() pulls the coordinates of the last value. E.g. can be used to add a point to the end of the line.
- geom_label_last_value_repel(): ggrepel versions for crowded plots with multiple lines
New dataset: population_german_states
label_skip() for skipping axis labels, e.g. only label every second tick
re-export label_date() and label_date_short() from scales for date labels with a custom locale.
Improvements and bug fixes

new ggplot2 theme modification helpers:
- theme_mod_rotate_x_axis_labels(): rotate axis labels
- theme_mod_legend_position(): legend positioning
- theme_mod_remove_minor_grid() : remove minor panel grid lines (x, y or both) or all grind lines
geom_vline_year() now also supports year_breaks based on weeks. Since weeks don't fall on the same date every year.
tsibble now optional dependency to improve speed of first install
add plotly compatibility for geom_epicurve() and geom_epigantt()
scale_y_cases_5er(): rename to min.n (from n.min) for correct base::pretty() compatibility
Bug fixes and minor improvements

Update geom_epigantt(): Add auto-scaling for linewidth and update documentation
Add scale_y_discrete_reverse()
New dataset of a fictional hospital outbreak
geometric_mean(): Add an option to disable warnings
Minor fixes
