We typically use the color in choropleths to encode a numeric variable (e.g., GDP, net exports, average SAT score, etc) and the eye naturally perceives the area that a particular color covers as proportional to its overall effect. In todays example we want: Lets get this information in different columns. And here are the results of our previous modification. That means, we need to get a little imaginative to animate certain things, like a population pyramid chart (essentially a bar chart) using add_segments() (a scatter-based layer) instead of add_bars() (a non-scatter layer). You can even read data from clipboard, so cool. FIGURE 4.6: A map of U.S. population density using the state.x77 data from the datasets package. For more documentation on creating animations with Plotly, see https://plotly.com/python/#animations. instead, simply change the time_colargument in the function above. Although Plotly Express supports animation for many chart and map types, smooth inter-frame transitions are today only possible for scatter and bar; Plotly Express will not automatically compute the union of all x/y/color ranges, so these must be specified manually to avoid scale jumps across frames; Animated figures with Graph Objects Unfortunately, non-scatter traces currently dont work with plot_mapbox()/ plot_geo() meaning that, for one, raster (i.e., heatmap) maps are not natively supported., To see more examples of creating and using plotly.js integrated dropdown functionality to modify graphs, see https://plot.ly/r/dropdowns/, This is way more intuitive compared to older workflows based on, say using ggplot2::fortify() to obtain a data structure where a row to represents particular point along a feature and having another column track which point belongs to each feature (for example)., #> [7] "satellite-streets" "open-street-map", #> [9] "white-bg" "carto-positron", #> [11] "carto-darkmatter" "stamen-terrain", #> [13] "stamen-toner" "stamen-watercolor", 'https://plotly-r.com/data-raw/airport_locations.csv', 'https://plotly-r.com/data-raw/flight_paths.csv', # See how this GeoJSON URL was generated at, # https://plotly-r.com/data-raw/us-states.R, "https://gist.githubusercontent.com/cpsievert/", "cf5631bfd2e385891bb0a9788a179d7f023bf6c8/", # Workaround to make sure image download uses full container, # size https://github.com/plotly/plotly.js/pull/3746, # filter the world sf object down to canada, # coerce cities lat/long data to an official sf object, # http://spatialreference.org/ref/sr-org/7/, # http://spatialreference.org/ref/sr-org/7/proj4/, "+proj=moll +lon_0=0 +x_0=0 +y_0=0 +ellps=WGS84, James A.
