)
e_map_register_ui(name, json, async = FALSE)
Arguments
- e
An

e_map

Additional options passed to registerMap.

Details
e_map_register_p
is not truly a proxy as it does not require
a chart to function. While the function e_map_register_ui
is meant to
register the map globally in the Shiny UI, not that then json
must be accessible
from the UI (generally www folder).
Examples
if (FALSE) {
json <- jsonlite::read_json("https://echarts.apache.org/examples/data/asset/geo/USA.json")
