fortplot_figure_plots Module

Plot creation methods for figure_t

This module contains the core plot creation functionality extracted from fortplot_figure_core to achieve QADS compliance (<500 lines).

Single Responsibility: Handle creation of different plot types (line plots, contours, filled contours, pcolormesh, fill_between) Pie chart functionality is in fortplot_figure_pie.
