Mudar o raio para um único ponto no mapa de calor?
Aqui está como você cria a camada Heatmap na Api do Google Maps:
var data = [
{location: new google.maps.LatLng(59.4072, 24.7053),weight:0.8},
{location: new google.maps.LatLng(59.4372, 24.7473),weight: 1},
{location: new google.maps.LatLng(59.4372, 24.7493),weight:0.8},
{location: new google.maps.LatLng(59.483428, 24.841709),weight: 0.6},
{location: new google.maps.LatLng(59.483256, 24.846666),weight: 0.2},
{location: new google.maps.LatLng(59.409425, 27.278345),weight: 0.3}
];
heatmap = new google.maps.visualization.HeatmapLayer({
data: data,
radius: 10
});
Como pode ver, tem de indicar o raio na configuração Heatmap.
mas como posso especificar um raio diferente para uma única fonte (ponto) no mapa de calor?

Em teoria, pode-se fazer várias camadas de imagem de calor.

var data1 = [
{location: new google.maps.LatLng(59.4072, 24.7053),weight:0.8},
{location: new google.maps.LatLng(59.4372, 24.7473),weight: 1},
{location: new google.maps.LatLng(59.4372, 24.7493),weight:0.8},
{location: new google.maps.LatLng(59.483428, 24.841709),weight: 0.6},
{location: new google.maps.LatLng(59.483256, 24.846666),weight: 0.2},
{location: new google.maps.LatLng(59.409425, 27.278345),weight: 0.3}
];
Heatmap1 = novo google.mapa.visualizacao.( dados: data1, raio: 10 });
var data2 = [
{location: new google.maps.LatLng(59.4072, 24.7053),weight:0.8},
{location: new google.maps.LatLng(59.4372, 24.7473),weight: 1},
{location: new google.maps.LatLng(59.4372, 24.7493),weight:0.8},

{location: new google.maps.LatLng(59.409425, 27.278345),weight: 0.3}
];
Heatmap2 = novo google.mapa.visualizacao.(
dados: data2,
raio: 3
});
