rU =r$ ) Timeline aG
Create a layer from GeoJSON with time data to add to a map.
To add time data, you need to do one of the following:
* Add a 'start' and 'end' property to each feature. The start and end
can be any comparable item.
Alternatively, you can provide a `get_interval` function.
* This function should be a JsCode object and take as parameter
a GeoJson feature and return a dict containing values for
'start', 'end', 'startExclusive' and 'endExcusive' (or false if no
data could be extracted from the feature).
* 'start' and 'end' can be any comparable items
* 'startExclusive' and 'endExclusive' should be boolean values.
Parameters
----------
data: file, dict or str.
The geojson data you want to plot.
get_interval: JsCode, optional
Called for each feature, and should return either a time range for the
feature or `false`, indicating that it should not be included in the
timeline. The time range object should have 'start' and 'end' properties.
Optionally, the boolean keys 'startExclusive' and 'endExclusive' allow the
interval to be considered exclusive.
If `get_interval` is not provided, 'start' and 'end' properties are
assumed to be present on each feature.
Examples
--------
>>> from folium.plugins import Timeline, TimelineSlider
>>> m = folium.Map()
>>> data = requests.get(
... "https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/all_day.geojson"
... ).json()
>>> timeline = Timeline(
... data,
... get_interval=JsCode(
... '''
... function (quake) {
... // earthquake data only has a time, so we'll use that as a "start"
... // and the "end" will be that + some value based on magnitude
... // 18000000 = 30 minutes, so a quake of magnitude 5 would show on the
... // map for 150 minutes or 2.5 hours
... return {
... start: quake.properties.time,
... end: quake.properties.time + quake.properties.mag * 1800000,
... };
... };
... '''
... ),
... ).add_to(m)
>>> TimelineSlider(
... auto_play=False,
... show_ticks=True,
... enable_keyboard_controls=True,
... playback_duration=30000,
... ).add_timelines(timeline).add_to(m)
Other keyword arguments are passed to the GeoJson layer, so you can pass
`style`, `point_to_layer` and/or `on_each_feature`.

Creates a timeline slider for timeline layers.
Parameters
----------
auto_play: bool, default True
Whether the animation shall start automatically at startup.
start: str, int or float, default earliest 'start' in GeoJson
The beginning/minimum value of the timeline.
end: str, int or float, default latest 'end' in GeoJSON
The end/maximum value of the timeline.
date_options: str, default "YYYY-MM-DD HH:mm:ss"
A format string to render the currently active time in the control.
enable_playback: bool, default True
Show playback controls (i.e. prev/play/pause/next).
enable_keyboard_controls: bool, default False
Allow playback to be controlled using the spacebar (play/pause) and
right/left arrow keys (next/previous).
show_ticks: bool, default True
Show tick marks on the slider
steps: int, default 1000
How many steps to break the timeline into.
Each step will then be (end-start) / steps. Only affects playback.
playback_duration: int, default 10000
Minimum time, in ms, for the playback to take. Will almost certainly
actually take at least a bit longer -- after each frame, the next
one displays in playback_duration/steps ms, so each frame really
takes frame processing time PLUS step time.
