337141108,MDU6SXNzdWUzMzcxNDExMDg=,332,Sanely handle Infinity/-Infinity values in JSON using ?_json_infinity=1,9599,closed,0,,,12,2018-06-29T21:21:27Z,2018-07-24T04:53:20Z,2018-07-24T03:08:30Z,OWNER,,"It turns out if you load this CSV using `csvs-to-sqlite` you get an Infinity value in SQLite:

```
name,num
sasha,10
terry,Inf
cathy,0.5
```

`csvs-to-sqlite infinity-bug.csv infinity-bug.db`

I deployed this using:

```
datasette publish now infinity-bug.db --name=datasette-infinity-bug --install=datasette-vega
```

Datasette outputs that as `Infinity` in the JSON format, which causes JavaScript errors.

Demo
* https://datasette-infinity-bug.now.sh/infinity-bug-0d0224e/infinity-bug - HTML view works
* https://datasette-infinity-bug.now.sh/infinity-bug-0d0224e/infinity-bug.json?_shape=array - this outputs the following:

```
[
    {
        ""rowid"": 1,
        ""name"": ""sasha"",
        ""num"": 10.0
    },
    {
        ""rowid"": 2,
        ""name"": ""terry"",
        ""num"": Infinity
    },
    {
        ""rowid"": 3,
        ""name"": ""cathy"",
        ""num"": 0.5
    }
]
```

But... in Firefox that gets rendered like this:

And if you click the ""Show charting options"" button you get this error in the console:

```
