I switched the order so that checking the box shows the big budget films instead of removes them

| Binding: Adding Widgets to Drive Interactivity | ||
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
| With an understanding of the selection types and conditions, you can now add data-driven and logic-driven widgets (or "bindings") as input elements to the charts using the ``bind`` option. As specified by `Vega-lite binding <https://vega.github.io/vega-lite/docs/bind.html#input-element-binding>`_, bindings can be of three types: | ||
|
|
||
| 1. Point selections can be bound directly to an input element, *for example, a radio button.* | ||
| 2. Interval selections which can be bound to scale, *for example, zooming in on a map.* | ||
| 1. Point and interval selections can be used for data-driven interactive elements, such as highlighting and filtering based on values in the data. | ||
| 2. Sliders and checkboxes can be used for logic-driven interactive elements, such as highlighting and filtering based on the absolute values in these widgets. | ||
| 3. Interval selections can be bound to a scale, such as zooming in on a map. |

Does this restructuring make sense?

Sprung from discussion in #2871 and resolves #2856.
I tried to update the docs to better reflect the correct usage of these parameters as well as update the gallery examples to use checkboxes correctly (but @mattijn already committed most of that in #2871 already, so mostly docs left here).
