# NOT WORKING CODE, JUST TO ILLUSTRATE HOW THIS FITS IN PYTHON
from cartoframes.viz import Map, Layer
from cartoframes.data import Dataset
import pandas
# DATA ACQUISITION AND INGESTION
df = pandas.read_csv(csv_file)
carto_table = "my_data"
Dataset(df).upload(table_name=carto_table)
# DATA ANALYSIS AND TRANSFORMATION
sql = "SELECT ... SOME SPATIAL ANALYSIS"
dataset = Dataset.create_from_query(sql, carto_table)
# VISUALIZATION
m = Map([
Layer(
dataset,
```
color: ramp($column_name, bold)
width: 15
symbol: cross
```
)
])
# SHARE IT
m.publish()everything is related to everything else, but near things are more related than distant things"
you will learn from anyone, but you are more likely to learn from near folks than from distant ones"
