To analyze the relationship between the feature fibr_ter_06 and the target variable (chronic heart failure), we need to examine the frequency distribution of the feature values for each target class. 

Here is an analysis of the relationship:

For the target class "no" (indicating no chronic heart failure), the possible values of fibr_ter_06 include both "no" and "yes".

For the target class "yes" (indicating chronic heart failure), the possible values of fibr_ter_06 also include both "no" and "yes".

Based on this analysis, we can create the following dictionary:

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

This dictionary shows the possible values of fibr_ter_06 for each target class.
