Hierarchical Computation Measures Visualization

Your provided code snippet is structured and organized, exhibiting six main computation measures: TotalSales, AverageSalesPrice, PreviousYearAvgSalesPrice, AverageSalesPriceYoYDiff, Top5CustomersBaseOnSales, and AverageSalesPriceYoYDiffTop5. This can be visually represented in a hierarchical fashion, starting from the generic measures to more specific ones.

Before proceeding with the DOT notation, please note the following:

• The DOT language is primarily used for graphical representation of hierarchical and non-hierarchical relationships between entities or data. It does not inherently support commercial tools-based codes like DAX (Data Analysis Expressions) which your provided code is written in.
• The DOT language ideally suits system dependencies, computer networks, flowcharts, and other use-cases where visual representation benefits the understanding.

Given these restrictions, we'll follow a broad interpretation of your code structure in DOT language within the capabilities of DOT.

digraph G {
  "TotalSales" -> "AverageSalesPrice";
  "AverageSalesPrice" -> "PreviousYearAvgSalesPrice";
  "AverageSalesPrice" -> "AverageSalesPriceYoYDiff";
  "PreviousYearAvgSalesPrice" -> "AverageSalesPriceYoYDiff";
  "TotalSales" -> "Top5CustomersBaseOnSales";
  "Top5CustomersBaseOnSales" -> "AverageSalesPriceYoYDiffTop5";
  "AverageSalesPriceYoYDiff" -> "AverageSalesPriceYoYDiffTop5";
}

In this DOT graph, each node represents a computation measure and directed edges represent dependency for calculations. This graph follows a top-down approach; for instance, TotalSales is calculated first and is a dependency in calculations of AverageSalesPrice and Top5CustomersBaseOnSales.
