# #### New to Plotly?
# Plotly's Python library is free and open source! [Get started](https://plot.ly/python/getting-started/) by downloading the client and [reading the primer](https://plot.ly/python/getting-started/).
# <br>You can set up Plotly to work in [online](https://plot.ly/python/getting-started/#initialization-for-online-plotting) or [offline](https://plot.ly/python/getting-started/#initialization-for-offline-plotting) mode, or in [jupyter notebooks](https://plot.ly/python/getting-started/#start-plotting-online).
# <br>We also have a quick-reference [cheatsheet](https://images.plot.ly/plotly-documentation/images/python_cheat_sheet.pdf) (new!) to help you get started!
# 

# #### Version Check
# Note: 2D Histograms are available in version <b>1.9.12+</b><br>
# Run  `pip install plotly --upgrade` to update your Plotly version

# ### 2D Histogram with Slider Control ###

# Add slider controls to 2d histograms with the [postMessage API](https://github.com/plotly/postMessage-API).        
#                                                                                                                    See the [code on JSFiddle](https://jsfiddle.net/plotlygraphs/y9sdy76h/4/).                                        
#                                                                                                                   Watch [the 5 second video](https://raw.githubusercontent.com/plotly/documentation/gh-pages/all_static/images
