<h1 class="title"> Sacramento County 311 Calls by Zipcode Up to Date API call</h1>
<p>Sacramento County 311 handles all County municipal service requests that are not police and fire related.
this map and bar chart makes up to date request from http://data.saccounty.net/home api
the data automatically updates when the api is updated. If the website is left open the api is called every 15 min<p>
