Elevation & Bathymetric Lines on Maps in Tableau

Topoghraphic and bathymetric maps have been known for a long time and are widely used in the world. On topographic maps, the lines connect points of equal elevation. On bathymetric maps, they connect points of equal depth. In this article I'll show how modern data visualization tools help build such interactive maps.

Optimal Transport Problem with Python and Tableau

The optimal transport problem or the Monge-Kantorovich transportation problem is a linear programming problem about the optimal transportation plan from departure points to destination points, with minimal transportation costs. Solving transport problems has a huge role in economics. In this article I will show how to solve such problems using an example and describe how you can visualize the results of a solution.

Ordering Chaos

Sometimes it seems to us that the processes that surround us are chaotic, but this is far from always the case, and in random events one can find certain patterns of process behavior, collecting data from this process and analyzing it.
In this blog post I’d like to talk about how you can see certain patterns in events that at first glance seem chaotic.

Contour Plot and Density Estimation in Tableau

The Contour Plot visualization and its special case Tanaka Contours meet in sports analysis and geo-analysis. Contours or levels in visualizations describe the same values, allowing you to represent, for example, elevation levels on maps. This article shows how you can create visualizations in Tableau that show changes in event density or event probability.

Joy Plot on the Map in Tableau

Disclaimer: Joy Plots in Tableau are not always the best option for analytical and business cases, but you can use them in bespoke visualizations. In any case, you can extend your knowledge about Tableau by creating such types of charts. In this article we will discuss about a type of geodata visualization in which values…

Animated Streamgraph in Tableau

A streamgraph, or stream graph, is a type of stacked area graph which is displaced around a central axis, resulting in a flowing, organic shape. Areas display changes in the values by category over time. This article describes creating of this type of chart in Tableau.

3D Models in Tableau

The blog post describes approaches to creating three-dimensional models in Tableau. 3D Models are not a common way of using Tableau, but they can be a great way to explore Tableau’s capabilities and deepen your knowledge of the platform

Parametric Portraits in Tableau

Math is beautiful!
The goal of the article is to show to Tableau users that math it is not only boring numbers and it is possible to describe anything by math equations and draw it.
It’s hard to imagine the dataset for the visualization of portraits contains only 2 values: 0 and 500. The portrait’s curves draw by using parametric equations for X and Y axes.
