How does an Echart graph diagram locate a node, from a Javascript and then enlarge the chart to display the node information?

this topic should be very detailed, my main purpose is to set up a search box to search all graph points, and then find that echart can automatically navigate to that point in chart and zoom in.
personally, I think we should first get the name of a node through the search box, find the location through the data information used when creating the chart, then enlarge the image and locate it.
now I don"t know what to do with the last sentence. Does anyone have any hints?


how is your graph laid out? Is layout 'force'' or 'none''?
