![](https://cdn-images-1.medium.com/max/1024/1*cyXw0NcnSCj-QItapHsyig.jpeg)Nowadays, the amount of data grows exponentially, and the more information we see, the harder it gets to process it. That’s why we need data visualization — in charts and dashboards, preferably interactive. It helps us humans save a lot of time and effort to view, analyze, and understand data, and make the right, informed decisions based on&nbsp;that.

![](https://cdn-images-1.medium.com/max/1024/1*7SYBgrbNOfbD45I3NRxeKA.jpeg)When you tend to use one library for a certain period of time, you get used to it. But, you need to evolve and learn something new every day. If you are still stuck up with Matplotlib(Which is amazing), Seaborn(This is amazing too), Pandas(Basic, yet easy Visualization) and Bokeh, You need to move on and try something new. Many amazing visualization libraries are available in python, which turns to be very versatile. Here, I’m going to discuss about these amazing libraries:

![](https://hackernoon.com/hn-images/1*0nJvs2Fj4N7QeNs1_6UnBA.jpeg)Unsupervised learning may sound like a fancy way to say “<em>let the kids learn on their own not to touch the hot oven” </em>but it’s actually a pattern-finding technique for mining inspiration from your data. It has nothing to do with machines running around without adult supervision, forming their own opinions about things. Let’s demystify!

![](https://hackernoon.com/hn-images/1*NdogWzOiwx-R79JYMy-S0w.png)Say, you’re building a Django-powered web application and you have some data you want to visualize. How do you do it? The most popular option is to pick a front-end charting library, have the back-end send the dataset (either through an API or directly passing it to the template) to the front-end, and render the chart in the browser. This approach allows the front-end to do most of the heavy lifting, thereby reducing the strain on your server.

![](https://hackernoon.com/hn-images/1*EjpEqgeu6QpIbkfDOnneiw.png)It’s summer in our nation’s capital. The humidity and the political climate are unbearably oppressive, and the denizens of D.C. do not give a fuck — at least, not literally. How do we know? I, along with fellow data scientist Rebecca Meseroll, collected over 10.7 million tweets from the contiguous 48 states and found out that ‘fuck’ appears in approximately 21 out of every 1000 tweets. In other words, slightly over 2% of all American tweets contain at least one variant of the word ‘fuck.’ Our analysis reveals a dearth of fucks in the District relative to the rest of the nation; the local fuck frequency in D.C. is a scant 11.7 per 1000 tweets. Language in other locales is not so chaste, however. Wyomingites, Californians, and Nevadans liberally peppered their tweets with profanity, exceeding 25 fuck-containing tweets per 1000 — more than twice their D.C. counterparts.
