For this article’s purposes, we will give an example using a bar chart since it is a good choice to encode two categorical variabl... | ['Data Visualization', 'Data Science', 'Plotly', 'Charts', 'Python'] |
Как создать дашборд с помощью Plotly
В этом разделе мы создадим дашборд с помощью Plotly, который будет отслеживать криптовалютный портфель тестового аккаунта в реальном времени и изменять его общую стоимость в зависимости от получаемых данных.
Вот как будет выглядеть финальная версия дашборда. Детали внешнего вида м... | ['Cryptocurrency', 'Binance', 'Nuances Of Programming', 'Data Science', 'Plotly'] |
Coding While Rolling a Stone Uphill
I can honestly say this project was the most challenging project I have participated in, to date. Throughout the entire project our team faced constant challenges, including: access to the initial code we would be taking over took several days, which hampered our initial planning be... | ['React', 'Lambda School', 'JavaScript', 'Plotly', 'Lessons Learned'] |

Data Visualizations Must Accept Some Uncertainty
Before developing a data visualization app, think about what’s more important, time or space. Do you want to display real-time data? Or do you want to analyze clean data? While developing my app, I wanted both. I became frustrated until... | ['Data Science', 'Plotly', 'Dashboard', 'Python', 'Data Visualisation'] |
ggplotly() — the most bang for buck function in the extended tidyverse
I’m a big fan of the tidyverse and ggplot. The tidyverse is an excellent framework for exploratory data analysis and ggplot is awesome. The ability these tools provide to import data, reshape it and visualise it is extremely powerful.

My Workflow with Jupytext
I will take the example of a typical day at work. Today, I have to answer a new question about our data and algorithms. It turns out that I already answered a similar question in the past. So, to begin, I search which of my existing notebooks is the closest to yield the answer to today’s ques... | ['Jupyter Notebook', 'Pycharm', 'Plotly', 'Visual Studio Code', 'Version Control'] |
It appears that those with higher levels of education are less likely to respond to an offer. Similar to the first graph, it appears that customers with luxury vehicles are less likely to respond to an offer.
How can we further explore the seemingly negative correlation between wealth and response rate?

There are several graphing libraries available to Python coders. Two of the most popular ones are Matplotlib and Plotly. Picking the right library depends on your situation. I recreated the OHLC (open-high-low-close) chart in both libraries to highlight these differences and included the code below.

Matplotlib vs. Seaborn vs. Plotly
Clear, effective data visualization is key to optimizing your ability to convey findings. With various packages in use such as Matplotlib, Seaborn, and Plotly, knowing the capabilities of each and the syntax behind them can become bewildering.

Placing ourselves in context
Picture an e-commerce platform. It provides services. Users start to sign up. Some of them are frequently interacting, some of them leave after a month or two. How do we summarise this behavior?
