Using the Tomtom Javascript Web API, how can a list of zipcodes be plotted on a map?
Would also be nice to increase/decrease the plotted point (pin) size based on a measure associated
with each zipcode - this is optional.
Been able to plot zipcodes on a map (using approx. long/lat for each).
Now after adding a few locations, how can they all be viewed - a bounding region for the locations
must be defined somehow, such that the TT API knows how to fit all locations on a viewable map.
Using the WEB API:
https://api.tomtom.com/maps-sdk-for-web/cdn/6.x/6.5.0/maps/maps-web.min.js
Here is an example:
var bounds = new tt.LngLatBounds();
locations.forEach(function(point) {
bounds.extend(tt.LngLat.convert(point));
});
map.fitBounds(bounds, { duration: 0, padding: 50 });
Getting back to “increase/decrease the plotted point (pin) size”:
what do you want to place as a pin? a geojson shape or an image?
both can have different sizes, so while drawing them you can specify somehow the size based on available data

Thankyou very much.
The API call ‘tt.LngLat.convert(point)’ expects a geo point ({lng:x,lat:y}).
Is there a conversion offered in web TT API that will take a zipcode and return a geo point {lng:x,lat:y} ?

To get coordinates of a zip code you can try with Geocoding:
Just put a zip code in query field.
