Antibiotic Usage in Livestock

Overview

This interactive tool allows users to explore data on antibiotic usage across various countries over multiple years. This app provides visual insights through interactive tables and graphs. In an era where antibiotic resistance is a growing concern, understanding trends and patterns in antibiotic use in animal agriculture is critical.

Features

• Interactive Table: Explore detailed data on antibiotic usage by country and year.
• Bar Chart: Visualize the comparison of antibiotic usage between countries.
• Trend Line: Observe the trend of antibiotic usage over the years for selected countries.
• Summary Statistics: View summary statistics of antibiotic usage for selected countries.
• Data Download: Download the filtered dataset for offline analysis.
• Search Function: Search for specific countries to filter the data.
• Interactive Data Points: Hover over data points in the bar chart and line chart for detailed information.

Data Source

The data used in this app is sourced from the open datasets provided by the Our World in Data project, specifically the dataset on antibiotic usage in livestock by the European Commission & Van Boeckel et al.

The data is filtered to exclude countries with only a single year of data to enable analysis of trends over time. I looked at countries with multiple data points across years to allow for a more accurate assessment of changes in antibiotic usage.
