In a method, a client device may be caused to provide an interactive display to the customer. The display may include controls usable by the customer to select different coverage combinations for a hypothetical policy, and an insurance premium quote for the hypothetical policy. Each control may enable the customer to adjust coverage for a different coverage type, be associated with a control graphic, and include a respective set of radio buttons distributed along a line within the control graphic. Each radio button may correspond to a different coverage level. The client device may also be caused to display, each time the customer adjusts a control by selecting a new radio button, a current selection indicator at the new radio button. The client device may also be caused to set, each time the customer selects a new coverage combination, the premium quote to a value corresponding to the new combination.
