This tutorial is divided into 2 in which it is explained how to design a mini SCADA or graphical representation of a process in this case a tank which displays the variable level 0 to 100% was created.
The web server will be located in Module ESP8266 which publishes an HTML page which in turn designs SVG file hosted on the server.

Step 1: SVG Editor Online - Components and Materials Required for Testing
Step 2: Design Scada SVG ESP8266 Part 1
Step 3: Linearization Rectangle Dimensions
Animation code in Arduino IDE
Map function is used 2 times:
1 Linearized (y-axis) min max 98 317, equivalent to 0 and 100% will wonder why the min is greater than the maximum, this is due to displacement requires the rectangle.
2 Linearize (Height) min 0 max 220, equivalent to 0 and 100%. to determine the ranges of 2 variables videos there is the method of animation is indicated.
3 Conversion Int to Strings These integer values must be converted to Strings and must concatenate the design SVG.
