Scattergrams

[thugulike]

Does any kind soul know of a way I can use an outline of the mainland UK and place dots upon it to show locations? Online would be good as I have a lot to do and if I could use postcodes as locators it would be even better.
I am trying to show the location of competitors at dog shows for one breed. Each show will need a separate scattergram.
I really don't need to do all that by hand, it would take forever.

If you google .... Map creator UK .... you will find a few options. I haven't used any of them myself, but they look like they have potential to add locations and markers.

Thanks Maydup, I'll give it a try
