build an interactive map with R Shiny

Job ID: 31195195

Budget: $250 – $750 USD

Here is the project idea: I need an interactive map of Europe that shows the number of my contacts ( Contact file has: Name, Street, ZIP Code, City, Country, Tel, email, last meeting etc) as dots. More contacts per region should result in a larger dot incl. the number of contacts. By zooming in more graduality should be shown until the level of correct street ( one dot only ).
Three more details are important:
- Since my contacts are growing I need a way to update them easily for R. Ideally not in the code but in a separate file such as Excel etc.
- Each contact has a Category; dots should show this by a different colour
- Filtering is needed for contact criteria ( name, ZIP code, country, category )
