GDP Growth Animated Bar Chart

This chart was generated in Google Colaboratory. Raw Data from IMF open source.

Install Package:

! pip install bar_chart_race

Import Libraries:

import pandas as pd
import numpy as np
import bar_chart_race as bcr

Read Dataset:

df = pd.read_excel("gdp.xlsx")
df

Shape Dataset (Rows to Columns, Columns to Rows):

df.set_index("Country", inplace=True)
df = df.T
print(f"Dataframe has {df.shape[0]} rows and {df.shape[1]} columns")
df.head()

Change data type 'object' to 'numeric':

df = df.apply(lambda x: pd.to_numeric(x, errors='coerce') if x.dtype == "object" else x)

Animated Bar Chart Generation (10 bars):

bcr.bar_chart_race(df, n_bars = 10)

There are still plenty of adjustments can be made for the visualization. It's just an example of how easy to create animated chart.
