Create & render

The functions viz_create and viz_render are essential for initializing a map, visualizing its content, and exporting it. They form the core workflow for creating maps with the geoviz R package.

viz_create(): Create a geoviz map container
viz_render(): Display the map
viz_save(): Save the map

Base Map and Structure

Functions that define the map’s geographic content, including outlines, tiles, and graticules.

viz_path(): Path layer
viz_outline(): Outline layer
viz_graticule(): Graticule layer
viz_rhumbs(): Rhumb lines layer
viz_tissot(): Tissot indicatrices
viz_earth(): Earth raster layer
viz_tile(): Mercator tiles

Map Decorations and Annotations

Functions for styling and annotating the map, such as titles, scale bars, and north arrows.

viz_header(): Map title
viz_footer(): Source of the map
viz_north(): North arrow
viz_scalebar(): Scale bar
viz_text(): Texts and labels
viz_minimap(): Minimap inset layer

Thematic

These functions allow the creation of thematic maps based on statistical data, complete with their associated legends.

viz_prop(): Proportional symbols layer
viz_choro(): Choropleth layer
viz_typo(): Typology layer
viz_propchoro(): Proportional + choropleth combined layer
viz_proptypo(): Proportional + typology combined layer
viz_picto(): Pictogram layer

Thematic (advanced)

These functions allow the creation of advanced thematic maps based on statistical data, complete with their associated legends.

viz_gridprop(): Grid-based proportional symbols layer
viz_gridchoro(): Grid-based choropleth layer
viz_smooth(): Smoothed density (isobands) layer
viz_dotdensity(): Dot density layer

marks

Behind the symbolization functions, there are elementary graphical marks. In geoviz, it is possible to use them directly.

viz_circle(): Circle layer
viz_square(): Square layer
viz_spike(): Spike layer
viz_halfcircle(): Half-circle layer
viz_symbol(): Symbol layer

effects

Since the maps created are in SVG format, it is possible to apply filters to them. These functions offer four different options for doing so.

viz_shadow(): Shadow layer
viz_blur(): Blur filter
viz_clipPath(): ClipPath layer
viz_radialGradient(): Radial gradient
viz_pattern(): Pattern layer
viz_sketch(): Sketch layer

Legends

Functions to design map legends

viz_leg_box(): Add a box legend
viz_leg_typo_vertical(): Add a vertical typology legend
viz_leg_typo_horizontal(): Add a horizontal typology legend
viz_leg_choro_horizontal(): Add a horizontal choropleth legend
viz_leg_choro_vertical(): Add a vertical choropleth legend
viz_leg_gradient_vertical(): Add a vertical gradient legend
viz_leg_spikes(): Add a spike legend
viz_leg_circles(): Add a proportional circles legend
viz_leg_circles_nested(): Add a nested proportional circles legend
viz_leg_squares(): Add a proportional squares legend
viz_leg_squares_nested(): Add a proportional nested squares legend
viz_leg_mushrooms(): Add a proportional half-circles (mushrooms) legend
viz_leg_symbol_vertical(): Add a vertical symbol legend
viz_leg_symbol_horizontal(): Add a symbol horizontal legend
