## Usage
similar to the example file

**column settings**

pts_setting (about the data, should be set according to data frame):

- xcor: x coordinate column,
- ycor: y coordinate column, and
- time: the time column, integer

xcor and ycor will be used to calculate distance, so probably not longitude and latitude, should be projected according to the region

```python
pts_setting = {'xcor':'xcor', 'ycor':'ycor', 'time':'days'}
```

**main parameters**

setting the three major parameter (should be set by user):
- s_radius: spatial searching radius
- T1: the time buffer, neighboring pair relationship
- T2: the time threshold, the shifting link relationship

```python
import pandas as pd
import tapitas

adf = pd.read_csv('test_data/demo_0905.csv', index_col=0)
pts_setting = {'xcor':'xx', 'ycor':'yy', 'time':'time'}
s_radius = 500
T1 = 6
T2 = 23
PG_graph = tapitas.Point_Diffusion(adf, pts_setting=pts_setting, s_radius=s_radius, T1=T1, T2=T2, resample_time=99, confidence_level=0.8, critical_value=None)
print("calculation done")

res = PG_graph.results
print(res.get_summary_df())
print(res.get_node_df())
print(res.get_cluster_df())
print(res.get_progress_df())
print(res.get_final_slinks_df())
print(res.get_final_nlinks_df())
```
