After finding the ID, you can then initialize it and declare it to a variable and only then you will have access to many of the chart's functionality and properties.

<script>
$(document).ready(function() {
    //Declare the eChart
	var theChart = echarts.init(document.getElementById('echarts_3C18B399268D4E4593DED6E06FF03376'));
    });
});
</script>

A good starting point to make something interactable is to make it be able to detect a click!

    theChart.on('click', function(params) {
      	console.log("Click!");
    });

The code above is one way to make the chart react to being clicked!

<script>
$(document).ready(function() {
    //Declare the eChart
	var theChart = echarts.init(document.getElementById('echarts_3C18B399268D4E4593DED6E06FF03376'));
    });

	//Detect click
     theChart.on('click', function(params) {
      	console.log("Click!");
    }); 
});
</script>

One simple interactive feature would be to make the user redirect to another site when they click on the EChart. The code below is an implementation of such.

<script>
$(document).ready(function() {
    //Declare the eChart
	var theChart = echarts.init(document.getElementById([ID HERE]));
    });

	//Redirect after click
     theChart.on('click', function(params) {
     	url = "google.com";
     	document.location.href = url;
    }); 
});
</script>

An interactive EChart also has the ability to redirect the user to another chart, where the information in the other chart will dynamically change depending on which part of the EChart the user clicked.

<script>
$(document).ready(function() {
    //Declare the eChart
	var theChart = echarts.init(document.getElementById([ID HERE]));
    });

	//Redirect after click
    theChart.on('click', function(params) {
      	url = [OTHER CHART'S URL LINK] + "?" + params.name;
      	document.location.href = url;
    });
});
</script>

A way to make the other chart receive information is to bring it through the urlURL. By accessing accessing params' properties, it will have the property "name" which includes the name of the data the user has clicked on. This information can then be brought to the url URL as a parameter (usually separated with a '?')  which then the other chart can access.

To access the parameter in the urlURL, we can use hash variables to do so, more specifically, the hash variable #request.queryString#.

Below is an example code of using the hash variable, to see it's its full functionality and purpose, download the demo app

SELECT
	a.c_email as "Email",
	COUNT(a.c_email) as "Amount"
FROM
	app_fd_book_meeting_room a
JOIN
	app_fd_create_meeting_room b
ON
	a.c_room_id = b.id
WHERE
	b.c_room_ID = "#request.queryString#" and 
	a.c_status = "accept"
GROUP BY
	a.c_email, b.c_room_id
