3️⃣ MINUTE⏲️BAR CHART
In the next three minutes, you will build a professional bar chart from scratch.
There is an interesting article on Medium titled "Tutorial on Building a Professional Bar Graph in Plotly Python" that shows how to build a very nice plot using Kaggle data.
Below the very cool plot complete with plot message. We want to do something similar, from zero, in under three minutes.
1 - GET DATA (45 seconds)
Go to the article, click on the link to the data, download the data as a csv file.
2 - OPEN DATASET AND RENAME COLUMNS (45 seconds)
Right-click on the file and open it in Excel. Rename the "created_at" column as "Date". Close and save the file. If you have time, you can rename the "category_name_1" column into "category"
3 - LOAD DATASET ON 'MPARANZA.COM APP (30 seconds)
Open the upload widget and load the file.
Wait until the little munchkin has finished running.
Scroll down to the submit button.
4 - RUN CHARTING (10 seconds)
This chart will appear below the submit button.
Nice, but there is no plot message ☹️.
5 - ADD PLOT MESSAGE (50 seconds)
Make up a message - max 100 characters. For example, "Growth driven by doubling of Mobiles sales, Appliance & Entertainment also strong" for the "by category" chart.
Type your message in the text box that above the chart. Click again on submit when done.
Click on submit.
Now the chart has a message above the title 😎.
