PyBloqs is a flexible framework for visualizing data and automated creation of reports.

It works with Pandas, matplotlib and highcharts. PyBloqs creates atomic blocks containing text, tables (from Pandas DataFrame), plots (matplotlib or highcharts) or images. All blocks can be styled with CSS. Each block can be created and displayed separately for fast development turnover. Lists of blocks can be stacked together to form reports. Reports can be displayed as HTML in the browser or exported in a variety of formats (including HTML, PDF, SVG, PNG).

Quickstart

Install PyBloqs

See the documentation for installation instructions.

Using PyBloqs

from pybloqs import Block, HStack, VStack
import pandas as pd
from matplotlib import pyplot as plt

text_block = Block('This is a text block', styles={'text-align':'center', 'color':'blue'})
text_block.show()

df = pd.DataFrame([[1., 2.],[3.,4.]], columns =['a', 'b'])
table_block = Block(df)
table_block.show()

plot_block = Block(plt.plot(df['a'], df['b']))
plot_block.show()

plot_and_table = HStack([plot_block, table_block])
report = VStack([text_block, plot_and_table])
report.show()
report.save('report.pdf')

Configuration

You can specify per-user default parameters in a yaml-formatted file ~/.pybloqs.cfg. This config file allows you to setup a call setup and login sequence against an smtplib.SMTP object. The following works for Google gmail - more detailshere.

smtp_kwargs:
  host: smtp.gmail.com
  port: 587
smtp_pre_login_calls:
- !!python/tuple
  - ehlo
  - {}
- !!python/tuple
  - starttls
  - {}
- !!python/tuple
  - ehlo
  - {}
smtp_login:
  user: me@gmail.com
  password: a_secret
public_dir: /tmp
tmp_html_dir: /tmp
user_email_address: me@gmail.com
