Modify a script to overlay a heatmap onto a Google Map on my website. The heat values will change daily, stored within MySQL as latitude, longitude, name, and heat value. Here's the link to the sample script ([login to view URL]). The end product must include the following:
* A dropdown menu listing country names. When a country is selected, the Google map will navigate to that country.
* A checkbox to turn on/off the heatmap
* A Google Map object embedded into the website
* A Heatmap overlay (see sample Google code)
* The heat values must be retrieved from a MySQL server (provided by the website host, [login to view URL])
* A database in the MySQL server with the table to be queried by the heatmap. The table should have a minimum of the following fields: ID, Heat Event Name, Heat Event Description, Latitude, Longitude, Heat Value
