Creating a Config file

Start by making a myoptions.json file that looks like the following:

{
"columns": {
    "latitude_column": "latitude",
    "longitude_column": "longitude",
    "time_column": "date"
}
}

Where “latitude” is the name of the column of latitude values, “longitude” is the longitude column, and “date” is the column of timestamps.

Now, let’s decide which components we want to see! GeoViz has a lot of Features, so take some time to look through them. Let’s say that we want to see the month-to-month frequency and the one year map features. According to the features page, we need to make sure that we have:

• the time column for the month-to-month frequency feature (done!)

• the latitude, longitude, and time columns for the one year map feature (also done!)

Now we need to add all_months and one_year to our options file. Let’s do that:

{
"columns": {
    "latitude_column": "latitude",
    "longitude_column": "longitude",
    "time_column": "date"
},
"features": [
    "all_months",
    "one_year"
]
}

Note that we put all_months and one_year in the “features” block, separate from the “columns” block.

If we look at the One Year Map feature, we see that there’s some additional options. If we have a column called “victim” whose value we want to see when we hover over its datapoint, we can add it like so:

{
"columns": {
    "latitude_column": "latitude",
    "longitude_column": "longitude",
    "time_column": "date"
},
"features": [
    "all_months",
    "one_year"
],
"features_customizations": {
    "hover_text_columns": [
        "victim"
    ],
},
}

If we wanted to add a filter column, we could also add it to the “features_customizations” block with

"features_customizations": {
    "hover_text_columns": [
        "victim"
    ],
    "filter_one_year_column": "victim"
}
