Make data for HeatmapWithTime

Input data format

Input JSON format on each NDJSON line:

• ts: Time stamp label (in any format)
• system_id: system_id from system_information.json
• status: Array of [station_id, num_bikes_available, num_docks_available] from station_status.json
• stations (Optional): {station_id: [lat,lon,name], ...} from station_information.json

Input data example:

{"ts":"2024-08-15T00:02","system_id":"docomo-cycle","status":[["00000001",4,16],["00000002",0,6],...],"stations":{"00000001":[38.269793,140.874203,"04.ドコモ東北ビル"],...}}
{"ts":"2024-08-15T00:02","system_id":"hellocycling","status":[["17",2,6],["26",10,0],...],"stations":{"17":[35.707252,139.777587,"新御徒町ステーション"],...}}
{"ts":"2024-08-15T00:32","system_id":"docomo-cycle","status":[["00000001",5,15],["00000002",0,6],...]}
{"ts":"2024-08-15T00:32","system_id":"hellocycling","status":[["17",2,6],["26",10,0],...]}
...

Output data format

• times: Time index array
• series: {series_id: [latLonWeightsAtTime0, latLonWeightsAtTime1, ...]}
  • latLonWeightsAtTimeX: [[lat,lon,num_bikes_available,num_docks_available],[lat2,lon2,bikes2,docks2],...]

(The format of `series[series_id]` value is same as `data` parameter of folium.plugins.HeatMapWithTime(). `times` is same as `index` parameter of folium.plugins.HeatMapWithTime().)

Output data example:

    "times": ["2024-08-15T00:02", "2024-08-15T00:32", ...],
