Price Visualization Ideas

  1. Interactive Price Trend Graphs:
    • Product-Specific: Show price fluctuations over time for a single product across different stores or regions. Users could select a date range or zoom in on specific periods.
    • Product Category: Display average price trends for a category of products (e.g., milk, bread) to see how prices evolve over time.
  2. Price Comparison Heatmaps or Tables:
    • Store-Specific: For a chosen product, show a color-coded grid or table comparing prices across different stores. This could be sortable by price or filtered by store type (e.g., supermarket, discount).
    • Regional: Compare average prices for the same product across different regions or cities to reveal geographic price disparities.
  3. Product Availability Maps:
    • Store Locator: Allow users to search for a specific product and see which nearby stores carry it, with price information overlaid if available.
    • Product Distribution: Visualize on a map the concentration of different brands or product types across regions.
  4. Advanced Product Comparison Tools:
    • Price per Unit/Serving: Compare prices per kilogram, liter, or serving size for similar products.
    • Integrated Scores: Incorporate Nutri-score, NOVA, and Eco-score alongside price information, allowing users to make informed choices considering both health and cost.
    • Brand Comparison: Highlight price differences between national brands, retailer brands, and budget options for the same type of product.
  5. Price Correlations and Insights:
    • Ingredient-Price Scatterplot: Create scatterplots to visualize potential correlations between the presence of certain ingredients (e.g., meat, organic) and product price.
    • Quality Label Impact: Compare average prices of products with and without specific quality labels (e.g., organic, fair trade) to quantify their impact on price.
  6. Shrinkflation Detection:
    • Product Weight/Volume Tracking: Monitor changes in product weight or volume over time while keeping price constant, to identify instances of shrinkflation (reducing product quantity while maintaining the same price).
  7. Price Data Collection Enhancements:
    • Mobile App Gamification: Encourage users to contribute targeted price data through a mobile app with gamification elements like rewards, badges, or leaderboards.
    • Crowdsourced Store Inventory: As a byproduct of price collection, gather information about product availability in stores and make this data accessible to users.
  8. Geographic Price Variation Analysis:
    • Choropleth Maps: Use color-coded maps to display average prices of specific products or categories across different regions.
    • Price Difference Calculation: Allow users to compare prices between two locations for the same product or product category.
  9. Price Basket Analysis:
    • Compare Shopping Baskets: Users could input a typical shopping list and see how the total cost would vary across different stores or brands.
  10. Price Alerts and Notifications:
    • Personalized Price Tracking: Users could set alerts for specific products or categories and receive notifications when prices drop below a certain threshold.

Additional Ideas:

  • Integrate with External Data: Combine Open Food Facts data with external sources like inflation rates or consumer price indices to provide broader context.
  • Customizable Dashboards: Allow users to create personalized dashboards with their preferred price visualizations and comparisons.
