Based on prior knowledge, exercise-induced angina refers to the chest pain or discomfort that occurs during physical exertion or exercise. It is often associated with coronary artery disease, which is a type of heart disease. 

To analyze the relationship between the feature "ExerciseAngina" and the task of whether the coronary angiography shows heart disease, we can look at how the presence or absence of exercise-induced angina relates to the likelihood of heart disease.

Here, we can create the following dictionary:

```json
{
	"no": ["N"],
	"yes": ["Y"]
}
```

The value for the "no" key is the list ["N"] which represents the possible values of the feature "ExerciseAngina" when the target class is "no" (no heart disease). Similarly, the value for the "yes" key is the list ["Y"] which represents the possible values of the feature "ExerciseAngina" when the target class is "yes" (heart disease).

Since there are only two categories in the feature "ExerciseAngina" (N and Y) and it is expected that exercise-induced angina would be associated with heart disease, it is not necessary to include any additional values in the dictionary.
