d3.js标记聚类

Question

我正在使用类似于此的正交变焦和可旋转地球：https://www.jasondavies.com/maps/rotate/。我需要计划大约20,000点。有没有办法聚类标记类似于使用Leaflet的方式？

我当前的地球仪使用SVG，其中每个点都是＆＃34;路径＆＃34;元素与＆＃34; d＆＃34;值。

＆＃13;

＆＃13;

player = AVAudioPlayerNode()

    let file = try! AVAudioFile(forReading: url)
    let buffer = AVAudioPCMBuffer(PCMFormat: file.processingFormat, frameCapacity: AVAudioFrameCount(file.length))

    do {
        print("read")
        try file.readIntoBuffer(buffer)
    } catch _ {
    }

engine.attachNode(player)
engine.connect(player, to: engine.mainMixerNode, format: nil)

self.player.scheduleBuffer(buffer, completionHandler: {
    print("Complete")
})

        engine.prepare()
    do {
        try engine.start()
    } catch _ {
        print("Play session Error")
    }

    player.play()
