# prefviz 0.1.3

* Fixed `dop_bar()` to order columns correctly and have y axis look nicer.

# prefviz 0.1.2

* Added `pairwise_calculator()` to compute all head-to-head comparisons from ranked preference data, returning a `"pairwise"` S3 object with TCP ratios, raw win counts, and Condorcet winner/loser detection.
* Added `pairwise_heatmap()` to visualise pairwise results as a red–green diverging heatmap, with tile annotations for TCP percentages or raw vote counts.
* Added `dop_bar()` to plot the preference distribution for a single contest round as a bar chart, supporting both wide and long input formats.
* `get_tern_data()` split into `get_tern_data2d()` (2D plots) and `get_tern_datahd()` (HD plots).
* `get_tern_datahd()` now returns the full data frame with a `labels` column, replacing the need for `get_tern_labels()`.
* `get_tern_labels()` is deprecated; use `get_tern_datahd(ternable)[["labels"]]` instead.

# prefviz 0.1.1

* Fixed `helmert_transform()` to use `geozoo::f_helmert()` correctly.
* Updated package description to reflect expanded scope.
* Addressed CRAN reviewer comments: improved documentation and examples across multiple functions, added `data.R` documentation for bundled datasets, removed internal `sysdata.rda`.

# prefviz 0.1.0

* First release.
