This demonstrates simple filtering - just showing those greenspaces that include a playground and with which the assessor was satisfied.
var getJSON = require("async-get-json");
var greenspaces = await getJSON("https://greenspacehack.com/data/sites_grouped.geojson");
var playgrounds = greenspaces.features.filter(feature => feature.properties['R1P'].includes("Yes"))
var good_playgrounds = playgrounds.filter(feature => feature.properties['NESTLIKERT'].includes("Very Satisfied") || feature.properties['NESTLIKERT'].includes("Satisfied"))
We can output the results as an HTML table, too.
var rows = good_playgrounds.map(function(feature) {
return `<tr><td>${feature.properties.name}<td>${feature.properties.town}`;
});
`<table>${rows.join('')}</table>`
