Based on my prior knowledge, the relationship between age and the presence of heart disease can be analyzed as follows:

Typically, as a person gets older, their risk of developing heart disease increases. However, it is important to consider that heart disease can also occur at a younger age due to various factors such as genetics, lifestyle, and underlying health conditions.

Based on this analysis, the dictionary representing the relationship between age (feature) and the presence of heart disease (task) can be generated as follows:

```json
{
    "no": [28.0, 35.0, 40.0, 45.0, 50.0],
    "yes": [55.0, 60.0, 65.0, 70.0, 75.0]
}
```

Note: The specific age values provided in the dictionary are hypothetical and may vary depending on the dataset and population under consideration.
