+
+Purpose:
+To handle and display date and time data in Chart.js scatter and bubble charts with type: 'time' on the x-axis.
+
+Why We Use It:
+1. Date Parsing and Formatting:
+- Enables robust parsing and formatting of date strings using the moment library.
+
+2. Chart.js Compatibility:
+- Integrates with Chart.js for time-based data handling.
+- Necessary for using type: 'time' in chart configurations.
+
+3. Advanced Date Manipulation:
+- Provides functions for date manipulation like adding/subtracting time and calculating date differences.
+
+Example Usage:
+To use type: 'time' for the x-axis in scatter and bubble charts:
+
+const config = {
+    type: 'scatter',
+    data: {...},
+    options: {
+        scales: {
+            x: {
+                type: 'time',
+                time: {
+                    unit: 'day'
+                }
+            }
+        }
+    }
+};
+
+The moment adapter ensures accurate processing and display of date and time data in Chart.js.
