Feature Styling by Attribute

On the map there are four points representing the path of a truck along a highway. The color is determined by the speed attribute attached to the feature object (red if its speed is over 55, orange between 36 to 55, and green less than 35).

In addition, the opacity of the symbol is determined by the fuel attribute (expressed as a ratio of 100).

The heading attribute is used to set the rotation of the point.
