The data part is in the format `timestamp, numberOfVotes`. To hold this in a class, I would need something like:

`
public class Whatever
{
    public int Timestamp{get;set;}
    public int NumberOfVotes{get;set;
}
```

This gets output to JSON as:

```
{"Timestamp":1367366400000, "NumberOfVotes":1104}
```

To make it work, it would need to be serialised as:

```
[1367366400000, 1104]
```

This uses no field names, and square braces instead of curly ones.
