Leaflet.js を使って GeoJSON データを地図上に表示してみる その1 - Qiita
で下ごしらえしたGeoJSONファイルを使用

#JavaScript

index.js
//. 掛川城の緯度経度(初期位置)
var lat = 34.77530283508074;
var lng = 138.01500141620636;

var map = null;
var marker = null;

$(function () {
  //. 掛川城を中心とした地図を OpenStreetMap データで表示
  map = L.map('map').setView([lat, lng], 15);
  L.tileLayer(
    'http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
      attribution: 'Map data &copy; <a href="http://openstreetmap.org/">OpenStreetMap</a>',
      maxZoom: 18
    }
  ).addTo(map);

  $.getJSON('./convertcsv.geojson', function (data) {
    var geojson = L.geoJson(data, {
      onEachFeature: function (feature, layer) {
        var field = '名称: '+feature.properties.name+ '<br>'+
        '住所: '+feature.properties.address+ '<br>'+
        '電話番号: '+feature.properties.tel+ '<br>'+
        '<a href="'+feature.properties.url+ '" target="_blank">ホームページ</a>';

        layer.bindPopup(field);
      }
    });
    geojson.addTo(map);
  });
});
