Tableau Dashboard

Business Formation Data

Tableau is a great data visualization tool used through the industry. Let's use business formation data given by https://www.census.gov/econ/bfs/csv/bfs_monthly.csv to build a quick and dirty tableau dashboard. We will use Python to do a little data cleaning and transforming to make it workable.

Let's use cURL to download data to a local folder.

curl -O https://www.census.gov/econ/bfs/csv/bfs_monthly.csv

Let's use Python to do some quick data transformation and cleaning to make it readable. We will use BeautifulSoup to scrape the NAICS wiki-table to build a dictionary to make the NAICS sector column readable.

import pandas as pd
from bs4 import BeautifulSoup
import requests as r
import re
df = pd.read_csv('data/bfs_monthly.csv')
url = r.get('https://en.wikipedia.org/wiki/North_American_Industry_Classification_System').text
soup = BeautifulSoup(url)

Let's scrape.

table = soup.findAll('table' ,attrs={'class':'wikitable'})
t = table[2]
items = t.findAll('td')
data = []
for x in items:
    if len(x.text)>0:
        data.append(x.text.replace('\n',''))
def splitter(x):
    if '-' in x or '/' in x:
        return re.split('[-:,/:]',x)[0]
    else:
        return x
d = {}
for a, b in pairwise(data):
    a = splitter(a)
    d[a]=b
def converter(x):
    if 'NAICS' in x and any(map(str.isdigit,x))==True:
        sec = x.split('NAICS')[1]
        sector = d[sec]
        return sector
    else:
        pass
