Hello Guys,This is a Line Chart Animation Visualization I made in Python (plotly). Comparatively speaking, choroplethmapbox is more powerful because you can fully specify the feature collection using GeoJSON, but the choropleth trace can be a bit easier to use if it fits your use case. Along with data and layout, frames can be added as a key in a figure object. Its possible to achieve the same effect using plot_ly() or plot_mapbox(), but the relevant marker/line/polygon data has to be put into an sf data structure before rendering (see Section 4.2.1 for more details). An introduction to the Dash web application framework. Rnaturalearth: World Map Data from Natural Earth.
